Support multiple schemas

[kmjennison]

When multiSchema is enabled, it's possible to have tables of the same name in different schemas. Right now, prisma-kysely will export the DB interface with duplicate properties.

It would be great to namespace the tables with their schema, such as my_other_schema.example_table. (This is what kysely-codegen does.)

Same here, this is a big blocker for me because I have to go in manually after each generation and update the schemas

#110 fixes this!
