Did you set "constraint_exclusion = on", then comment it
"#constraint_exclusion = on" in the .conf file? If so, then
ProcessConfigFile() will ignore this line since it is a comment, instead
of setting back its value to "off". Try to do set "constraint_exclusion =
off" explicitely, see if long delay ever happens.

Btw, is this considered a bug of ProcessConfigFile()? To fix it, we can
call InitializeGUCOptions() somewhere but I am not sure which values
should be untouched, like ConfigFileName ...
