NAME

       SHOW - show the value of a run-time parameter

SYNOPSIS

       SHOW name
       SHOW ALL

DESCRIPTION

       SHOW  will  display  the  current setting of run-time parameters. These
       variables  can  be  set  using  the  SET  statement,  by  editing   the
       postgresql.conf configuration file, through the PGOPTIONS environmental
       variable (when using libpq or a libpq-based  application),  or  through
       command-line  flags  when  starting  the  postgres  server.  See in the
       documentation for details.

PARAMETERS

       name   The name of  a  run-time  parameter.  Available  parameters  are
              documented  in  in  the  documentation  and  on the SET [set(7)]
              reference page. In addition, there are a few parameters that can
              be shown but not set:

              SERVER_VERSION
                     Shows the server’s version number.

              SERVER_ENCODING
                     Shows the server-side character set encoding. At present,
                     this parameter can be shown  but  not  set,  because  the
                     encoding is determined at database creation time.

              LC_COLLATE
                     Shows  the  database’s locale setting for collation (text
                     ordering). At present, this parameter can  be  shown  but
                     not  set,  because  the  setting  is determined at initdb
                     time.

              LC_CTYPE
                     Shows  the  database’s  locale  setting   for   character
                     classification.  At  present, this parameter can be shown
                     but not set, because the setting is determined at  initdb
                     time.

              IS_SUPERUSER
                     True if the current role has superuser privileges.

       ALL    Show   the   values   of   all  configuration  parameters,  with
              descriptions.

NOTES

       The function current_setting produces equivalent  output;  see  in  the
       documentation.   Also,  the  pg_settings  system view produces the same
       information.

EXAMPLES

       Show the current setting of the parameter DateStyle:

       SHOW DateStyle;

       Show the current setting of the parameter geqo:
