apgdiff (1)

Usage: apgdiff [options] <old_dump> <new_dump>

Another PostgreSQL Diff Tool is a simple PostgreSQL diff tool that is useful for schema upgrades. The tool compares two schema dump files and creates an SQL output file that is (after some hand-made modifications) suitable for upgrades of old schemata.

--version

--add-defaults

adds DEFAULT ... in case new column has NOT NULL constraint but no default value (the default value is dropped later)

--add-transaction

adds START TRANSACTION and COMMIT TRANSACTION to the generated diff file

WARNING: this may cause functions to appear to be same in cases they are not, so use this feature only if you know what you are doing

--output-ignored-statements

outputs information about DDL statements that apgdiff ignores at this moment (it will not output any SELECT, INSERT, UPDATE and/or DELETE statements)
