you can do error tests in the fixtures

I mean specifically on this error annotation. They're super easy to set up a test for, it's like this where a test fixture has a comment specifically for a reported error

Thanks - specifically I was interested in the inherited LiteralValueMixin that has the restriction "Cannot use time literal in expression"?
As both PostgreSql + ansiFixtures are run by the tests - I can't override it in the PostgreSql dialect to support the syntax
updatedAt > CURRENT_TIMESTAMP - INTERVAL '30' days - The timestamp-literal will always run and currently fails if I override the restriction in LiteralValueMixin.
I looked at the Fixture setup and I don't think it will override the ansi test cases even if I redeclare the test fixture timestamp-literals in postgreSql fixtures.
Hopefully - that makes sense and is for another PR once I understand it :)
Bind arg test is easiest to debug Add Integration test for PGInterval type
Override literal_value to support interval_expression “INTERVAL ‘1 day” is the literal expression that will be used by the TypeResolver This creates a new PostgresLiteralValue that inherits the base LiteralValueMixin LiteralValueMixin may have to be customised to support returning CURRENT_DATE_TIME etc. The base behaviour only allows assignments of timestamps.
The SqlLiteralExpr will be “INTERVAL ‘1 day’” Add CURRENT_ types to return actual types -ansi inherited was TEXT Calls the inherited “ansi” behaviour for NULL etc There is probably a better way to achieve this in future PRs as there is more to do

Used for debug
closes #4144 Look into approach for supporting INTERVAL literal column results
SELECT INTERVAL '1 day';Override Literals, test returns
PGIntervaltype.TODOs
Literals for CURRENT_DATE, CURRENT_TIME, CURRENT_DATE_TIME should also be considered.
Support
SELECT NOW() + INTERVAL '1 day';
