Is there something I am missing here? Perhaps. You can EXPLAIN ANALYZE a SELECT, just like i/u/d -- but then you don't get the normal result set back. Is that what you mean? You can turn on log_min_duration_statement and get total SELECT duration logged. There's a thread in pgsql-hackers ("Re: Porting MSSQL to PGSQL: trace and profile") about server-side logging of query plans and stats (for all four of s/i/u/d), which is indeed not there in PG. -- Engineers think that equations approximate reality. Physicists think that reality approximates the equations. Mathematicians never make the connection.
