[Pg] Add missing support for vector, point types to drizzle-zod

[saevarb]

Currently, drizzle-zod excepts any column that has a dataType as "array" to be an array that also has a baseColumn. This turns out to not be true for types such as vector and point, among others.. which results in passing an undefined where none is expected which leads to a runtime crash.

This PR adds a test that replicates the crash, and adds support for vector and point -- and there might be other types which could be supported similarly easily.

It also detects the case that was causing a runtime crash and now throws a more useful error message, which would easily flag future cases where the solution is probably just adding yet another is check. This is solely based on my own preference, however, so definitely not dying on a hill for that commit.

I also noticed that the resulting types for the schemas were wrong, which I attempted to fix. The result seems very clunky though.

Finally, as an additional optional and very benign improvement, I modified the expectSchemaShape to output the names of the keys that fail to match for easier debugging.

Fixes #2424

Would love this to be fixed 🙏
