With the current CVS, initdb calls pg_snprintf() on my platform which doesn't support %$ natively on my libc printf. Now, initdb could pull from pgport itself but I think it pulled from libpq first. Perhaps we should reorder how those libraries appear in the link line but I think that would fix just this case, not the more general one of pg client apps. > > The bottom line is that we only used to require major libpq version > > bumps when we changed the libpq API.

We had the problem with 8.0.X where we remove get_progname from libpq and psql and friends were pulling that from libpq in the past for 7.4. > Also, I think it's alot better to actually do soname changes to > libraries if things can break.

Yes, that is where I am leaning in this discussion because libpgport varies much more frequently than the libpq API. However, changing the link order should fix that so let me do that and see if it helps. -- Bruce Momjian | http://candle.pha.pa.us pgman@candle.pha.pa.us | (610) 359-1001 + If your life is a hard drive, | 13 Roberts Road + Christ can be your backup. | Newtown Square, Pennsylvania 19073 ---------------------------(end of broadcast)--------------------------- TIP 2: you can get off all lists at once with the unregister command (send "unregister YourEmailAddressHere" to [EMAIL PROTECTED])
