Hello,
When query is executed in function that has language set to "sql" then
parameters passed to it are not considered as either externally supplied
parameters or constants as far as partitioning goes. It will scan all
partitions, despite parameters clearly limiting it to just one.

Rick,
I am glad I could help, but I am not quite sure you understand the
purpose/use of the trigger to
partition the table.
The trigger merely decides which child should get the data, the "query" is
not passed, only the data,

Melvin, thanks. Syntax was indeed the problem there. Any idea how to pass the
original query to the child table? My insert has 113 parameters passed in,
but based on the constraint violations I am seeing, it seems they are not

Hi Jim,
I'm not going the partitioning route because I want to, I'm just out of
options at this point. As this table gets bigger, performance just gets
worse over time. I wanted to try partitioning to see if it helps.
Thanks for the tip, looking at the function again what you suggest makes

If you're going to go this route, depend on how IF ELSIF operates and

Only 8.2 or newer has CREATE INDEX CONCURRENTLY.
Maybe you could schedule a maintenance window for this.

What is the effect of reindexing a partition on the inherited table?
For example I have a table 'test' with partitions 'test_01_07',
'test_02_07', 'test_03_07', 'test_04_07', corresponding to data from
January 2007, February 2007, and so on. I noticed that when I run a
