Postgres Backend
Connection pool
NewPostgresOptions starts the pgx pool with 16 connections (DefaultMaxConns).
This is a starting point for the default worker parallelism; set
options.PgOptions.MaxConns explicitly for the deployment's worker count and
PostgreSQL connection budget.
Testing
By default, the postgres tests are skipped. To run the tests, set the environment variable POSTGRES_ENABLED to true before running the tests and have a postgres server running on localhost:5432 with a database named postgres and a user postgres with password postgres.
