d6d317d as solved the issue of tablespace paths across multiple nodes
with the new GUC called allow_in_place_tablespaces, and is getting
successfully used in the recovery tests as of 027_stream_regress.pl.
Shouldn't we rely on that rather than extending more our test perl
modules? One tricky part is the emulation of readlink for junction
points on Windows (dir_readlink in your patch), and the root of the
problem is that 0003 cares about the path structure of the
tablespaces so we have no need, as far as I can see, for any
dependency with link follow-up in the scope of this patch.
This means that you should be able to simplify the patch set, as we
could entirely drop 0001 in favor of enforcing the new dev GUC in the
nodes created in the TAP test of 0002.
Speaking of 0002, perhaps this had better be in its own file rather
than extending more 011_crash_recovery.pl. 0003 looks like a good
idea to check after the consistency of the path structures created
during replay, and it touches paths I'd expect it to touch, as of
database and tbspace redos.
+ if (!reachedConsistency)
+ XLogForgetMissingDir(xlrec->ts_id, InvalidOid);
Not sure to understand why this is required. A comment may be in
order to explain the hows and the whys.
