Re: Add sanity check for duplicate enum values in GUC definitions

Hello

> . While working on [1]. I added an enum-typed GUC

I wanted to check the original issue, but the linked patch adds a
boolean GUC (logical_replication_fallback_to_full_identity), I did not
see enum mentioned anywhere in the diff, did you link the correct
thread?

Maybe you could compile a utility executable as part of the build, and
execute it as part of the test suite?
