Due to Greenplum's MPP architecture, the postgres process needs to connect to databases, some symbols from libpq.so are compiled into the postgres binary as well. However, some symbols are not safe to be exported both in the postgres binary and the libpq.so library. E.g., some of the functions are using palloc()/pfree() to allocate/free memory in backend codes while using malloc()/free() in frontend codes. See issue #16219. This patch resolves the issue by hiding frontend symbols in the postgres binary, so that frontend symbols referenced in extensions will be resolved correctly. <!-- Thank you for your contribution to Apache Cloudberry (Incubating)! --> Fixes #ISSUE_Number ### What does this PR do? <!-- Brief overview of the changes, including any major features or fixes --> ### Type of Change - [ ] Bug fix (non-breaking change) - [ ] New feature (non-breaking change) - [ ] Breaking change (fix or feature with breaking changes) - [ ] Documentation update ### Breaking Changes <!-- Remove if not applicable.
