Interesting,
I have been getting failures on REL_14_STABLE:
t/012_subtransactions.pl ............. 11/12
# Failed test 'Rollback of PGPROC_MAX_CACHED_SUBXIDS+ prepared transaction on promoted standby'
# at t/012_subtransactions.pl line 211.
# got: '3'
# expected: '0'
t/012_subtransactions.pl ............. 12/12 # Looks like you failed 1 test of 12.
t/012_subtransactions.pl ............. Dubious, test returned 1 (wstat 256, 0x100)
Failed 1/12 subtests
And the logs, tmp_check/log/regress_log_012_subtransactions, showing:
### Enabling streaming replication for node "primary"

This is quite consistent for me, but only when I configure with --enable-coverage and --enable-dtrace. (I haven't yet
triedone of those without the other.)
I wasn't going to report this yet, having not yet completely narrowed this down, but I wonder if anybody else is seeing
this?
I'll try again on master....
