NAME

apgdiff - Another PostgreSQL Diff Tool

SYNOPSIS

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

DESCRIPTION

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.

OPTIONS

--version
displays apgdiff 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
--ignore-function-whitespace
ignores multiple spaces and new lines when comparing content of functions
 
•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
--ignore-start-with
