UNLOGGED is defigned in OptTemp in gram.y, so the parser accepts
CREATE UNLOGGED VIEW and CREATE UNLOGGED SEQUENCE, but they are
actually not supported.
=# CREATE UNLOGGED VIEW uv AS SELECT 1;
TRAP: FailedAssertion("!(relkind == 'r' || relkind == 't')", File:
"heap.c", Line: 1246)
=# CREATE UNLOGGED SEQUENCE us;
TRAP: FailedAssertion("!(relkind == 'r' || relkind == 't')", File:
"heap.c", Line: 1246)
The most easiest fix would be preventing them in parser level.
