cmd_type: Added missing DROP TABLE t2;
guc: Adjusted to match the updated settings view, which now display
boolean values as 'yes' and 'no', also added the 'options' column
to the output.
guc_1: Handle PostgreSQL versions <= 12 which don't have the
track_planning feature.
rows.out: Added missing DROP TABLE t2. Also removed the line 'ERROR:
relation "t2" already exists' since we fixed the problem in
cmd_type regression.
top_query: Handling both track = 'top' and track = 'all' cases.
top_query_1: On PostgreSQL >= 14 the sub query from the procedure is
stored as (select $1 + $2), whereas on PG <= 13 it is
stored as SELECT (select $1 + $2).
