Postgres issue with getting tables for a schema which has space in its name

[pavansandeep2910]

code:

const inspector = schemaInspector(knex);
inspector.withSchema('test schema')
await inspector.tables();

error:

SELECT
        rel.relname AS name
      FROM
        pg_class rel
      WHERE
        rel.relnamespace IN ('test schema'::regnamespace)
        AND rel.relkind = 'r'
      ORDER BY rel.relname

Looks like

SELECT
        rel.relname AS name
      FROM
        pg_class rel
      WHERE
        rel.relnamespace IN ('test schema'::regnamespace)
        AND rel.relkind = 'r'
      ORDER BY rel.relname

is throwing an error, whereas

SELECT
        rel.relname AS name
      FROM
        pg_class rel
      WHERE
        rel.relnamespace IN ('"test schema"'::regnamespace)
        AND rel.relkind = 'r'
      ORDER BY rel.relname

works as expected.

This should be able to be resolved by adding an additional set of quotes in these pieces:

knex-schema-inspector/lib/dialects/postgres.ts

Lines 89 to 91 in 20d6ad0

	const schemaIn = this.explodedSchema.map(
	(schemaName) => `${this.knex.raw('?', [schemaName])}::regnamespace`
	);

Wanna open a PR for that @pavansandeep2910?
