This commit extends the postgres_fdw_get_connections() function to include a new used_in_xact column, indicating whether each connection is used in the current transaction. This addition is particularly useful for the upcoming feature that will check if connections are closed. By using those information, users can verify if postgres_fdw connections used in a transaction remain open. If any connection is closed, the transaction cannot be committed successfully. In this case users can roll back it immediately without waiting for transaction end. The SQL API for postgres_fdw_get_connections() is updated by this commit and may change in the future. To handle compatibility with older SQL declarations, an API versioning system is introduced, allowing the function to behave differently based on the API version.
