I think doing PQinitSSL(new_value) is probably the least invasive change
to solve this, which is why I suggested it. It does have a compile-time
check by referencing the #define.

We never documented the valid values to PQinitSSL(), and no one ever
reported this as a bug, so the existing use of PQinitSSL() is probably
very small.
