  • This is a bug in Postgresql. Argh!
    So what are my options?
    Get the bug fixed. This is the advantage of using open source stuff: once developers know about a bug and have a good clue about what causes it, you often don't have to wait long for a fix.

    So, report it.

    Just permanent table for this use? I've done this when I wanted something I was doing repeatedly to go the fastest possible. I found there was some overhead to creating the temporary table, so I just created a permanent table and reused it.
    • That's the work around that I've done for now. Unfortunately it's a fair bit slower than the temporary table system, because it has to have an extra column (pid), which has to be permanently indexed, thus inserts are slower, and selects and updates are slower because they have to use the index. Nuts.
      • It's been a few years since I did that app where I replaced a temporary table with a permanent one and I recall that there were other advantages to making the data (semi-)permanent.

        I recall now that the real speedup was that the data was time-tagged. I had been performing big selects against the database for data, inserting data from a time range in the temporary table and performing reports off of this. I was able to take advantage of the fact that subsequent runs would need data mostly in the same time

  • PlPGSQL isn't the only embedded language. There's PL/TCL, PL/Python and PL/Perl as well. These may not have the same limitations as PL/PGSQL.
