Implement check_function_bodies only for Postgres

Here's a different implementation of #134 . Specs don't pass (not sure why yet), but this is simpler and only for PG.

[cmer]

Is this implementation more aligned with what you had in mind?

[cmer]

Any chance this could be merged in? Thanks!

I'm unsure I want to support this, because I have no context of the use-case or how it is supported in other databases (and therefore the other adapters).

[cmer]

From the previous PR:

Added a new configuration parameter check_function_bodies to allow controlling the database behavior when loading functions.

This is necessary if the function created relies on the existence of a table that is not yet created, for example.

Disabling check_function_bodies is pg_dump's default behaviour and, in my opinion, should be Fx's default behavior as well.

As mentioned, this is the default behavior of pg_dump and essential to load a schema that includes functions. Without this, creating a functions that depend on tables that are yet to be created fails (ie: will be created in a subsequent query from the schema).

Thanks @cmer - I need to do some reading on this and testing. Can't promise when or if that happens, but I will try.

[cmer]

Thanks! This would be game-changer TBH. Hope you see the value in it.

I am not sure about this. The docs say:

This parameter is normally on.

So maybe the default should be true here, with the possibility to set it to false for specific use cases?

[cmer]

You could do that. It's off by default for pg_dump from what I remember, and this gem is the closest thing to pg_dump so it seemed reasonable to follow the pg_dump conventions. Either way works. Just having the option would be a huge win!

See: https://dba.stackexchange.com/questions/284260/how-to-prevent-pg-dump-from-generating-set-default-table-access-method-heap -- it shows that false the default value for pg_dump.
