Обсуждение: Client side copy functionality

Tom,

with the since 7.4 deprecated copy support functions in libpq, is there 
any define or other way to figure out if compiling against a pre-7.4 or 
post-7.4 libpq?

Hm, don't think so.  If you've autoconfiscated your client code, you can
just put in a configure test for one of the newer libpq functions.

[ sounds of diff'ing ... ]  If you're desperate for an #ifdef solution,
it looks like you could test for the existence of one of the PG_DIAG_XXX
macros added to postgres_ext.h.  This seems a bit circuitous though.
