[TASK] Activate a impexp export functional test for postgres

A functional test has been skipped for postgres functional
test execution because it exported relations in not expected
order like other databases. Mainly younger postgres versions
are unreliable when undetermistic queries are used.

Undetermistic database query sorting may lead to unexpected
and random data returns. Generally queries should implement
determistic sortings to mitigate this issue across all
dbms and dbms versions.

The related query for this functional test has been already
made determistic through #95032 and #95045 but missed to
reactive this related functional test.

This patch acts as follow-up for #95045.
