Hi,
When building without assertions with a rather recent gcc (trunk built in the
last weeks), I get this warning:
../../../../../home/andres/src/postgresql/src/backend/utils/init/miscinit.c: In function
'SerializeClientConnectionInfo':
../../../../../home/andres/src/postgresql/src/backend/utils/init/miscinit.c:1102:36: warning: parameter 'maxsize' set
butnot used [-Wunused-but-set-parameter=]
1102 | SerializeClientConnectionInfo(Size maxsize, char *start_address)
| ~~~~~^~~~~~~
And the warning is right. Not sure why a new compiler is needed, IIRC this
warning is present in other cases with older compilers too.
The most obvious fix is to slap on a PG_USED_FOR_ASSERTS_ONLY. However, we so
far don't seem to have used it for function parameters... But I don't see a
problem with starting to do so.
Greetings,
Andres Freund
