This release comes with the following major change:
- Updated autogen.sh to fetch mongo-c-driver 1.17.3 and json-c 0.15. This allows us to support MongoDB server 4.4 now.
- Support for v9.5 is removed.
Other changes:
- Fixes crash with the queries involving LEFT JOIN LATERAL.
- Add JSONC_CFLAGS environment variable to cmake while building json-c library so that a few platform-specific environment variables can be exported.
- Restrict fetching PostgreSQL-specific system attributes from the remote relation to avoid a server crash.
- Refactor the WHERE pushdown code a bit to inline with the postgres_fdw code.
- Correct the exit status in autogen.sh. The script fails upon error and returns a non-zero return code.
- Fall back to cmake if cmake3 is not present so that the system having only cmake (with version required) can work without failure.
