Masahiko Sawada bd65cb3cd4 pg_logicalinspect: Fix possible crash when passing a directory path. ... Previously, pg_logicalinspect functions were too trusting of their input and blindly passed it to SnapBuildRestoreSnapshot(). If the input pointed to a directory, the server could a PANIC error while attempting to fsync_fname() with isdir=false on a directory. This commit adds validation checks for input filenames and passes the LSN extracted from the filename to SnapBuildRestoreSnapshot() instead of the filename itself. It also adds regression tests for various input patterns and permission checks.
