Re: Postmaster crashes on SIGHUP when oauth_validator_libraries holds only whitespace - Mailing list pgsql-bugs

Pushed with tiny bits of tweaking and with a backpatch down to 18. Thanks!

./daniel

The test addition coined with bca67e5a3 is not very robust,
unfortunately. Buildfarm animal serinus found a way to break it [1]
as below:
#   Failed test 'oauth_validator_libraries restored'
#   at /home/bf/bf-build/serinus/HEAD/pgsql/src/test/modules/oauth_validator/t/001_server.pl line 152.
#          got: '   '
#     expected: 'validator'
# Looks like you failed 1 test of 171.

I've managed to reproduce this locally with a sleep:
--- a/src/backend/utils/misc/guc.c
+++ b/src/backend/utils/misc/guc.c
@@ -569,6 +569,7 @@ ProcessConfigFileInternal(GucContext context, bool applySettings, int elevel)
                                                                        item->name, item->value)));
                        }
                        item->applied = true;
+pg_usleep(100000);
                }
                else if (scres == 0)
                {

It makes oauth_validator/001_server fail deterministically for me.

Could you take a look, please?
