Inspired by Charles' thread and the work of Emmanuel [1], I have made some experiments trying to create a trigger to make partitioning using C language. The first attempt was not good, I tried to use SPI [2] to create a query to insert into the correct child table, but it took almost no improvement compared with the PL/pgSQL code.
The right way to do this with SPI is to prepare each insert-statement on first invocation (SPI_prepare + SPI_keepplan), and reuse the plan after that (SPI_execute_with_args).
If you construct and plan the query on every invocation, it's not surprising that it's no different from PL/pgSQL performance.
