Ideally, when a database is created from a script, the indexes will
be left inactive until the data is loaded. That makes the load
more efficient and ends up with good statistics.

Procedures are compiled twice, once from PSQL to BLR and second
from BLR to an executable format. The plan is defined in the
second compilation, so it is created on first reference after
server startup.
