In 8.0 the pgcrypto functions were non-strict and checked for NULLs.

In 8.1 they were made STRICT.

In 8.2 the NULL check were removed from code.

That means if you use function signatures from 8.0 with
pgcrypto from 8.2, they will crash on NULL.

To fix it, just reinitialize functions: \i pgcrypto.sql
