It seems that the first test on the compression in pg_backup_tar.c is now obsolete.
It didn't make much sense anyway.
211 if (AH->compression < 0 || AH->compression > 9) 212 AH->compression = Z_DEFAULT_COMPRESSION;
213 214 /* Don't compress into tar files unless asked to do so */ 215 if (AH->compression ==
Z_DEFAULT_COMPRESSION)216 AH->compression = 0; 217 218 /* 219 * We don't support
compressionbecause reading the files back is not 220 * possible since gzdopen uses buffered IO which totally
screwsfile 221 * positioning. 222 */ 223 if (AH->compression != 0) 224
exit_horribly(modulename,225 "compression is not supported by tar archive format\n"); 226 }
