FWIW, Firebird doesn't have any form of schemas or cross-database
query support (although I think commercial third-party extensions might exist
for the latter).
You'll probably be best off explicitly providing schema names for your common
functions, e.g. SELECT * FROM common.mytable . Depending on your app,
that could be better from a security point of view in PostgreSQL as well,
if you want to prevent your users from sneakily replacing the common
database objects.
