pg_restore did not verify that zstd and LZ4 decompression completed the final frame when reading custom and directory-format dumps. As a result, it could accept a dump whose compressed data was truncated. Track final-frame completion and reject incomplete compressed input. For zstd, flush any internally buffered output before performing the final check. Add regression tests for truncated zstd and LZ4 data in custom and directory-format dumps and also address a potentially empty error message while in there.
