Re: Slot's restart_lsn may point to removed WAL segment after hard restart unexpectedly - Mailing list pgsql-hackers

Could you, please, check this patch?  On my system it makes 046 and
047 execute in 140 secs with -O0 and -DRELCACHE_FORCE_RELEASE
-DCATCACHE_FORCE_RELEASE.

Thank you for the patch!

It decreases the test's duration significantly:
# +++ tap check in src/test/recovery +++
t/046_checkpoint_logical_slot.pl .. ok
All tests successful.
Files=1, Tests=1, 29 wallclock secs ( 0.01 usr  0.00 sys +  0.23 cusr  0.56 csys =  0.80 CPU)

Without the patch:
t/046_checkpoint_logical_slot.pl .. ok
All tests successful.
Files=1, Tests=1, 519 wallclock secs ( 0.01 usr  0.00 sys +  3.05 cusr  7.64 csys = 10.70 CPU)
Result: PASS

Best regards,
Alexander
