Support for PostgreSQL partitioned tables

[avaly]

PostgreSQL supports native table partitioning. The intended way of using partitioned tables is to read from/update the main table.

When running pg-schema-cli on a database with a partitioned table, the output only contains the partitions of that table, but not the table itself:

Excerpt from the generated index.ts:

interface DatabaseSchema {
  posts_p0: { record: PostsP0Record; insert: PostsP0InsertRecord };
  posts_p1: { record: PostsP1Record; insert: PostsP1InsertRecord };
  posts_p2: { record: PostsP2Record; insert: PostsP2InsertRecord };

Because the main table posts does not show up in the generated TS files or the generated schema.json file, the pg-typed package does not return a table from tables() for the main posts table.

So, we can only interact with the individual partition tables through pg-typed.

The only way to interact with the main partitioned table is through raw SQL queries.
