That was my thought too. Old OpenSSL doesn't have SHA2 so why SHA2 is still blocked in pgcrypto? Is that by design or bug?
Thanks.

To be honest, pgcrypto actually falls back on built-in code for AES,
in case old OpenSSL that does not have AES. Thats because AES
should be "always there", together with md5/sha1/blowfish.
I do not consider SHA2 that important (yet?), so they don't
get same treatment.

Attached is a patch that re-defines SHA2 symbols so that they would not
conflict with OpenSSL.
Now that I think about it, if your OpenSSL does not contain SHA2, then
there should be no conflict. But ofcourse, if someone upgrades OpenSSL,
server starts crashing. So I think its best to always apply this patch.
