I say it ;). I've gone through all callers and checked. Not that that guarantees anything, but ... The reason a static buffer is better is that some of the *desc routines use relpathbackend() and pfree() the result. That would require providing a stub pfree() in xlogdump which seems to be exceedingly ugly. > > Change signature to return a 'const char *' to make misuse easier to > > detect. > > That seems to create way more churn than is necessary, and it's wrong > anyway if the result is palloc'd. It causes warnings in potential external users that pfree() the result of relpathbackend which seems helpful. Obviously only makes sense if relpathbackend() returns a pointer into a static buffer...
