Yep, but it's a bit awkward and time-consuming, and not quite suited to
ORM-generated requests since you got to generate all the plan names, when
the SQL query itself would be the most convenient "unique identifier"...
A cool hack would be something like that :
pg_execute( "SELECT ...", arguments... )
By inserting a hook which calls a user-specified function on non-existing
plan instead of raising an error, this could work.
However, this wouldn't work as-is since the plan name must be <=
NAMEDATALEN, but you get the idea ;)
