  1. Fix issue 2046: Memory leak during btree(agtype) (apache#2060) 

    Fixed the memory leaks during a btree index build.

The issue has to do with how PostgreSQL allocates and frees its
memory. Usually, contexts are destroyed, freeing up the memory in
that context for the functions.  However, sometimes this destruction
happens way too late for it to be helpful. In the case of btree
compare, the context destruction doesn't happen until after the sort
has completed. The solution is to add in pfrees to manage the memory
we use, ourselves.

Additionally, propagated these changes to a few other functions. More
PRs will be created to address other locations where this applies.

No regression tests were impacted.
No additionall regression tests are needed.
