Otherwise the owner of relations and such will depend on the username of
the user running the regression tests. As "postgres" is the most common
username for that purpose, hardcode that in pg_regress_multi.pl.
There already exist tests that locally embed knowledge about port
numbers, and there's more tests requiring that. Instead of copying
\set's to several tests, make these port number variables available to
all tests.
All citusdb references in
- extension, binary names
- file headers
- all configuration name prefixes
- error/warning messages
- some functions names
- regression tests
are changed to be citus.
