DESCRIPTION

This class provides a wrapper for the pg_dump utility.

METHODS

This class provides the following methods:

Pg::CLI::pg_dump->new( ... )

The constructor accepts a number of parameters:

• executable

  The path to pg_dump. By default, this will look for pg_dump in your path and throw an error if it cannot be found.

• username

  The username to use when connecting to the database. Optional.

• password

  The password to use when connecting to the database. Optional.

• host

  The host to use when connecting to the database. Optional.

• port

  The port to use when connecting to the database. Optional.

• require_ssl

  If this is true, then the PGSSLMODE environment variable will be set to "require" when connecting to the database.

$pg_dump->run( database => ..., options => [ ... ] )

This method dumps the specified database. Any values passed in options will be passed on to pg_dump.

This method also accepts optional stdin, stdout, and stderr parameters. These parameters can be any defined value that could be passed as the relevant parameter to IPC::Run3's run3 subroutine.

Notably, you can capture the dump output in a scalar reference for the stdout output.

$pg_dump->version()

Returns a the three part version as a string.

$pg_dump->two_part_version()

Returns the first two decimal numbers in the version.
