Hi,
while working on a support case I stumbled upon a bug in pg_upgrade.
Upgrade fails with "No such file or directory" when a database is
moved to a non-default tablespace and contains a table that is moved
to pg_default. The cause seems to be that the following test
incorrectly equates empty spclocation with database tablespace:
tblspace = PQgetvalue(res, relnum, i_spclocation);
/* if no table tablespace, use the database tablespace */
if (strlen(tblspace) == 0)
tblspace = dbinfo->db_tblspace;
Patch to fix this is attached.
Regards,
Ants Aasma
