NAME
pgcopydb - pgcopydb pgcopydb - copy an entire Postgres database from source to target
SYNOPSIS
pgcopydb provides the following commands: pgcopydb clone Clone an entire database from source to target fork Clone an entire database from source to target follow Replay changes from the source database to the target database snapshot Create and exports a snapshot on the source database + copy Implement the data section of the database copy + dump Dump database objects from a Postgres instance + restore Restore database objects into a Postgres instance + list List database objects from a Postgres instance + stream Stream changes from the source database help print help message version print pgcopydb version
DESCRIPTION
The pgcopydb command implements a full migration of an entire Postgres database from a source instance to a target instance. Both the Postgres instances must be available for the entire duration of the command. The pgcopydb command also implements a full Logical Decoding client for the wal2json logical decoding plugin, allowing Change Data Capture to replay data changes (DML) happening on the source database after the base copy snapshot.

PGCOPYDB VERSION
The pgcopydb version command outputs the version string of the version of pgcopydb used, and can do that in the JSON format when using the --json option. $ pgcopydb version pgcopydb version 0.8 compiled with PostgreSQL 12.12 on x86_64-apple-darwin16.7.0, compiled by Apple LLVM version 8.1.0 (clang-802.0.42), 64-bit compatible with Postgres 10, 11, 12, 13, and 14 In JSON: $ pgcopydb version --json { "pgcopydb": "0.8", "pg_major": "12", "pg_version": "12.12", "pg_version_str": "PostgreSQL 12.12 on x86_64-apple-darwin16.7.0, compiled by Apple LLVM version 8.1.0 (clang-802.0.42), 64-bit", "pg_version_num": 120012 } The details about the Postgres version applies to the version that's been used to build pgcopydb from sources, so that's the version of the client library libpq really.
