Subject: pg11+: pg_ls_*dir LIMIT 1: temporary files .. not closed at end-of-transaction
Date: Sun, 8 Mar 2020 12:31:03 -0500
Message-ID: <20200308173103.GC1357@telsasoft.com> (raw)
While working on a patch, I noticed this pre-existing behavior, which seems to
be new since v11, maybe due to changes to SRF.
|postgres=# SELECT pg_ls_dir('.') LIMIT 1;
|WARNING: 1 temporary files and directories not closed at end-of-transaction
|pg_ls_dir | pg_dynshmem
|postgres=# SELECT pg_ls_waldir() LIMIT 1;
|WARNING: 1 temporary files and directories not closed at end-of-transaction
|-[ RECORD 1 ]+-------------------------------------------------------------
|pg_ls_waldir | (00000001000031920000007B,16777216,"2020-03-08 03:50:34-07")
Note, that doesn't happen with "SELECT * FROM".
I'm not sure what the solution is to that, but my patch was going to make it
worse rather than better for pg_ls_tmpdir.
