Debian stable is somewhere around PG 7.4.x. But we were using SSL_CTX_set_client_cert_cb even in 7.4, and AFAICT the function has existed in OpenSSL since 1999 or earlier. I did some googling and found various people complaining of similar build problems with completely Postgres-unrelated software that's using OpenSSL, so it seems there's something a bit odd about that particular function ... but I didn't find out what. regards, tom lane
