NAME

       Test::DBIx::Class::SchemaManager::Trait::Testpostgresql - deploy to a test Postgresql
       instance

DESCRIPTION

       This trait uses Test::Postgresql58 to auto create a test instance of Postgresql in a
       temporary area.  This way you can test against Postgresql without having to create a test
       database, users, etc.  Postgresql needs to be installed (but doesn't need to be running)
       as well as DBD::Pg.  You need to install these yourself.

       Please review Test::Postgresql58 for help if you get stuck.

CONFIGURATION

       This trait supports all the existing features but adds some additional options you can put
       into your inlined of configuration files.  These following additional configuration
       options basically map to the options supported by Test::Postgresql58 and the docs are
       adapted shamelessly from that module.

       For the most part, if you have Postgresql installed in a normal, findable manner you
       should be able to leave all these options blank.

   base_dir
       Returns directory under which the postgresql instance is being created. If you leave this
       unset we automatically create a place in the temporary directory and then clean it up
       later.  Unless you plan to roundtrip to the same database a lot you can just leave this
       blank.

       Please note if you set this to a particular area, we will delete it unless you
       specifically use the 'keep_db' option.  SO be care where you point it!

       Here's an example use.  I often want the test database setup in my local testing
       directory, that makes it easy for me to examine the logs, etc.  I do:

               BASE_DIR=t/tmp KEEP_DB=1 prove -lv t/my-postgresql-test.t

       Now I can roundtrip the test as often as I want and in between tests I can review the
       logs, start the database manually and login (see the 'keep_db' section below for an
       example of how to do this).  Next time I run the tests the framework will automatically
       clean it up and rest the schema for testing.

       You may need to do this if you are stuck on a shared host and can't write anything to
       /tmp.  Remember, you can also put the 'base_dir' option into configuration instead of
       having to type it into the commandline each time!

       Note that if you override the BASE_DIR we will set the 'force_drop_tables' option to true
       to ensure that we properly clean the database before trying to install tables and
       fixtures.

   initdb and postmaster
       If your postgresql is not in the $PATH you might need to specify the location to one of
       there binaries.  If you have a normal postgresql setup this should not be a problem and
       you can leave this blank.

       If you have to set these, please note you need to set the full path to the required file,
       not just the path to containing directory.

NOTES

       The following are notes regarding the way this trait alters or extends the core
       functionality as described in the basic documentation.

   keep_db
       If you use the 'keep_db' option, this will preserve the temporarily created database
       files, however it will not prevent Test::Postgresql58 from stopping the database when you
       are finished.  This is a safety measure, since if we didn't stop a test generated database
       instance automatically, you could easily end up with many databases running at once, and
       that could bring your server or testing box to a halt.

       If you use the 'keep_db' option and want to start and log into the test generated database
       instance, you can start the database by noticing the diagnostic output that should be
       generated at the top of your test.  It will look similar to:

               # Starting postgresql with: /Library/PostgreSQL/8.4/bin/postmaster \
                -p 15432 -D /tmp/E4tuZF5uFR/data
               # DBI->connect('DBI:Pg:dbname=template1;port=15432','postgres',''])

       If you have specified the base_dir to use, this output will not be displayed by default.
       You can force it's display by setting tdbic_debug to true. eg.

           TDBIC_DEBUG=1 BASE_DIR=t/tmp KEEP_DB=1 prove -lv t/my-postgresql-test.t

       You can then start the database instance yourself with something like:

               ./Library/PostgreSQL/8.4/bin/postmaster -p 15432 \
               -D /tmp/E4tuZF5uFR/data &

       You will get output that looks like:

               [1] 1564
               LOG:  database system is ready to accept connections
               LOG:  autovacuum launcher started

       There will be some additional output to the term and then the server will go into the
       background.  If you don't like the extra output, you can just redirect it all to /dev/null
       or whatever is similar for your OS.

       You can now log into the test generated database instance with:

               psql -h localhost --user postgres --port 15432 -d template1

       You may need to specify the full path to 'mysql' if it's not in your search $PATH.

       When you are finished you can then kill the process.  In this case our reported process id
       is '1564'

               kill 1564

       And then you might wish to 'tidy' up temp

               rm -rf /tmp/E4tuZF5uFR

       All the above assume you are on a unix or unixlike system.  Would welcome document patches
       for how to do all the above on windows.

   Noisy warnings
       When running the Test::Postgresql58 instance, you'll probably see a lot of mostly harmless
       warnings, similar to:

               NOTICE:  drop cascades to 2 other objects
               DETAIL:  drop cascades to constraint cd_track_fk_cd_id_fkey on table cd_track
               drop cascades to constraint cd_artist_fk_cd_id_fkey on table cd_artist
               NOTICE:  CREATE TABLE / PRIMARY KEY will create implicit index "cd_pkey" for table "cd"

       In general these are harmless and can be ignored.

       If you like to avoid these messages, you could change your connect_info like this:

           connect_info => {
               dsn => 'dbi:Pg:dbname=dbname',
               user => 'user',
               pass => 'secret',
               on_connect_do => 'SET client_min_messages=WARNING;',
           },
