25 SQL::Translator::Parser::DBI::PostgreSQL - parser for DBD::Pg
29 See SQL::Translator::Parser::DBI.
33 Uses DBI methods to determine schema structure. DBI, of course,
34 delegates to DBD::Pg, and versions < 1.31 of DBD::Pg don't return very
35 useful information. It is recommended that you upgrade this module.
