The SPI_execute() documentation does mention that multiple commands
are allowed:
http://www.postgresql.org/docs/8.2/interactive/spi-spi-execute.html
"You may pass multiple commands in one string. SPI_execute returns
the result for the command executed last. The count limit applies
to each command separately, but it is not applied to hidden commands
generated by rules.
"When read_only is false, SPI_execute increments the command counter
and computes a new snapshot before executing each command in the
string."
Should that documentation be modified?
