Peter Eisentraut	3d9f7ec1ff	Add test case for collation mismatch in recursive query This isn't very important by itself, but was left on my list of things without test coverage for the collation feature.	15 years ago
Peter Eisentraut	b9cff97fdf	Don't allow CREATE TABLE AS to create a column with invalid collation It is possible that an expression ends up with a collatable type but without a collation. CREATE TABLE AS could then create a table based on that. But such a column cannot be dumped with valid SQL syntax, so we disallow creating such a column. per test report from Noah Misch	15 years ago
Peter Eisentraut	4442e1975d	When creating a collation, check that the locales can be loaded This is the same check that would happen later when the collation is used, but it's friendlier to check the collation already when it is created.	15 years ago
