Subject: pgsql: Make generate_queries_for_path_pattern_recurse() interruptible
Date: Fri, 14 Aug 2026 13:23:17 +0000
Message-ID: <E1wursS-00000000YPs-1Rq8@gemulon.postgresql.org> (raw)
Make generate_queries_for_path_pattern_recurse() interruptible
In case of a very long path pattern with each element pattern being
resolved to many graph elements
generate_queries_for_path_pattern_recurse() may take very long time to
generate all the possible graph paths. Make
generate_queries_for_path_pattern_recurse() interruptible so that a
user may be able to cancel such a query if required and the interrupts
are processed in timely manner.
