I'm sorry for the late reply. I'm currently reviewing autoprepare.
I could not make it in time for the commit fests in September,
but I will continue to review for the next commitfest.
Performance tests are good results. The results are shown below.
pgbench -s 100 -c 8 -t 10000 -S (average of 3 trials)
- all autoprepare statements use same memory context.
18052.22706 TPS
- each autoprepare statement use separate memory context.
18607.95889 TPS
- calculate memory usage (autoprepare_memory_limit)
19171.60457 TPS
From the above results, I think that adding/changing functions
will not affect performance. I am currently checking the behavior
when autoprepare_memory_limit is specified.
