CHANGES: Document array item type confusion fix
Tentative fix for error 'indexing the NULL value with "set_nonblocking'.
Certain operations on arrays of only objects could have triggered a type
confusion under some circumstances, causing integers to be freed as
objects, and thus a NULL derefence (SIGSEGV).
o Sql.pgsql - Ensure that the db connection is closed when the portal is closed.
