Propagate query IDs of utility statements in functions
For utility statements defined within a function, the query tree is
copied to a PlannedStmt as utility commands do not require planning.
However, the query ID was missing from the information passed down.
This leads to plugins relying on the query ID like pg_stat_statements to
not be able to track utility statements within function calls. Tests
are added to check this behavior, depending on pg_stat_statements.track.
This is an old bug. Now, query IDs for utilities are compiled using
their parsed trees rather than the query string since v16
(3db72ebcbe20), leading to less bloat with utilities, so backpatch down
only to this version.
