The grammar will only accept something syntactically similar to a function call in a function-in-FROM expression. However, there are various ways to input something that ruleutils.c won't deparse that way, potentially leading to a view or rule that fails dump/reload. Fix by inserting a dummy CAST around anything that isn't going to deparse as a function (which is one of the ways to get something like that in there in the first place). In HEAD, also make use of the infrastructure added by this to avoid emitting unnecessary parentheses in CREATE INDEX deparsing. I did not change that in back branches, thinking that people might find it to be unexpected/unnecessary behavioral change. In HEAD, also fix incorrect logic for when to add extra parens to partition key expressions. Somebody apparently thought they could get away with simpler logic than pg_get_indexdef_worker has, but they were wrong --- a counterexample is PARTITION BY LIST ((a[1])). Ignoring the prettyprint flag for partition expressions isn't exactly a nice solution anyway. This has been broken all along, so back-patch to all supported branches.

PostgreSQL tests ================ This directory contains a variety of test infrastructure as well as some of the tests in PostgreSQL. Not all tests are here -- in particular, there are more in individual contrib/ modules and in src/bin. Not all these tests get run by "make check".
