class CQL::Postgres::Driver

• CQL::Postgres::Driver
• DB::Driver
• Reference
• Object

Overview

Lets crystal-db open postgres:// and postgresql:// URLs with the wire driver, so CQL::Schema and DB.open use it unless another PostgreSQL driver (the pg shard) registered those names first. cockroachdb:// is opt-in (.register_cockroachdb, or compile with -Dcql_postgres_driver_cockroachdb) because only CockroachDB 24.3 was checked against a real server. crystal-db keeps its own pool; the options it owns are removed from the URL before the rest is read as a Config.

Defined in:

postgres/driver.cr
