NAME

SQL::Translator::Parser::DBI::PostgreSQL - parser for DBD::Pg

SYNOPSIS

See SQL::Translator::Parser::DBI.

DESCRIPTION

Uses DBI to query PostgreSQL system tables to determine schema structure.

CONFIGURATION

You can specify the following for "parser_args" in SQL::Translator :

deconstruct_enum_types

If set to a true value, the parser will look for column types which are user-defined Enums, and generate a column definition like:

{
  data_type => 'enum',
  extra => {
    custom_type_name => 'MyEnumType',
    list => [ 'enum_val_1', 'enum_val_2', ... ],
  }
}

This makes a proper round-trip with SQL::Translator::Producer::PostgreSQL (which re-creates the custom enum type if producer_args->{postgres_version} >= 8.003) and can be translated to other engines.

If the option is false (the default) you would just get

{ data_type => 'MyEnumType' }

with no provided method to translate it to other SQL engines.
