This thing calculates a fingerprint of DB structure.
The main function to call is a set-returning
trunkfingerprint.get_db_structure_hash(
p_level int default 0,
p_catalog regclass default null,
p_exclude_schemas name[] default '{}'
)
p_level could be
- 0 -- single fingerprint for the whole DB structure,
- 1 -- one value for each catalog,
- 2 -- a line per each catalog object.
p_catalog is optional. If set, only the specified catalog is explored.
p_exclude_schemas is an array of schemas to exclude from calculation.
Probably works with Postgres 9.4 only at the moment.
Run sudo make install to install it, and create extension trunkfingerprint; to add it to a particular database.
