Where, in libpq-fe.h?

The proposed names look fine to me except for

> W PG_DIAG_STACK_TRACE

This seems overly specific to my eyes --- I'd suggest PG_DIAG_CONTEXT,
or maybe someone can suggest another possibility. We don't promise to
provide a "stack trace" per se; there are already uses that don't
correspond to the user's idea of function nesting (for instance,
identifying the buffer associated with an I/O failure).
