* ext/dba/tests/setup/setup_dba_tests.inc: sort test output
Iterating through a database with firstkey() and nextkey() is
guaranteed to retrieve all rows, but apparently not in any particular
order. This is causing a test failure for at least one user, so we
steal the sort() approach from GDBM to ensure that the output is
predictable.
* ext/dba/tests/dba_*.phpt: sort expected test output
The actual output is now sorted for consistency, so we need to update
the expected output as well. As a nice side effect, some differences
in the expected outputs for the various engines have been eliminated.
Closes GH-14786
* ext/pgsql/tests/80_bug14383.phpt: sort expected test output
This test uses a routine from ext/dba that now sorts its (actual)
output, so we have to sort the expected output here as well.
* ext/dba/tests/setup/setup_dba_tests.inc: update comment
After doing some more digging, it looks like GDBM isn't the only
engine where the iteration order with firstkey() and nextkey()
might change unexpectedly.
