Message-ID: <E1wwXA1-000000019Td-2w7O@gemulon.postgresql.org> (raw)
psql: Fix psql slash option leaks
psql_scan_slash_option() returns a malloc'd string, but \getresults,
\gset in pipeline mode, \restrict, and \unrestrict did not free it
after consuming or copying the value.
Free these option strings after use.
Backpatch to all supported versions. In v17 and older, only \restrict
and \unrestrict are affected, so those branches need only that part of
the fix.
