PBCKP-2705: Adjust signal handling and compatibility for PostgreSQL 18
This patch adds compatibility changes for PostgreSQL 18:- Updated signal handler initialization in pgut.c to use sigaction() instead of pqsignal(), as pqsignal() now returns void.- Updated process_block_change() in backup.c to handle the new RelPathStr structure returned by relpathperm() in v18.- Updated CreateReplicationSlot_compat() in stream.c to support the new CreateReplicationSlot() signature introduced in v18.These changes ensure successful build and runtime behavior withPostgreSQL 18 while preserving backward compatibility with earlierversions.
