Hi all,

Coverity is pointing out a couple of resource leaks:
- In DropReplicationSlot@streamutil.c, query is leaked.
- In getTransforms@pg_dump.c, the alloced result of get_language_name is not free'd. Other code paths calling this routine do the job.
- In libpqGetCurrentXlogInsertLocation@libpq_fetch.c (pg_rewind), the value "val" returned by run_simple_query should be free'd. Other code paths do so.
- In libpqProcessFileList@libpq_fetch.c, a call to PQclear is missing for a query result.
- In vacuum_one_database@vacuumdb.c, a call to PQclear is missing.
Attached is a patch to address all those things. Backpatches would be good to have as well.
Regards,
--
