Add patches needed for compatibility with Postgresql 13, which are still under review upstream. Debug builds (BR2_ENABLE_DEBUG=y) fails because of warnings, so disable WARNINGS_AS_ERRORS.

Subject: [PATCH] Add compatibilty wrapper functions for base64
|
|
encoding/decoding
|
|
|
|
PG13 adds a destination length 4th argument to pg_b64_decode and
|
|
pg_b64_encode functions so this patch adds a macro that translates
|
|
to the 3 argument and 4 argument calls depending on postgres version.
|
|
This patch also adds checking of return values for those functions.
