in pl_comp.c, plpgsql_build_variable takes a pointer to a PLpgSQL_type structure, which is always a malloc'ed instance(since we always use plpgsql_build_datatype function). The switch statement in plpgsql_build_variable function elicits that its reference is only kept in case the type structure represents a PLPGSQL_TTYPE_SCALAR, otherwise it is not kept and needed in case its either PLPGSQL_TTYPE_ROW or PLPGSQL_TTYPE_REC.
So is it intensional or a memory leak?
Thank you

I think you need to take another look at the startup sequences. Those
modules are not run before MemoryContextInit. In any case, the odds
of running out of memory before we get to MemoryContextInit are so small
that I don't have a problem with crashing if it happens.
