The record

Purpose: pgtestdb is a Go library for database-backed tests that provisions an isolated, migrated Postgres database for each test.
Template databases: It runs migrations once to build a template database and clones that template for individual tests.
Speed: The README says creating a test database from a template takes on the order of 10 milliseconds.
Concurrency: Each test gets its own database, and the README says pgtestdb is concurrency-safe for parallel tests.
Cleanup and debugging: Databases from passing tests are deleted automatically, while a failed test leaves its database available and logs a connection string for inspection.
Migration integrations: Built-in adapters are listed for pgmigrate, golang-migrate, goose, dbmate, Atlas, sql-migrate, Bun, and Tern; custom migrators are also supported.
Database drivers: The library uses Go's database/sql interface and supports pgx, lib/pq, or another database/sql driver.
Postgres requirement: Users must provide a running Postgres server; the README describes Docker, native installations, and remote servers as options.
Permissions: The configured server user needs capabilities to create databases and roles, and the README recommends using a dedicated testing server rather than production.
Default test role: The default role used for test databases has NOSUPERUSER, NOCREATEDB, and NOCREATEROLE capabilities, so it cannot create extensions by default.
Database limits: The README notes that highly parallel test suites can exceed a Postgres server's connection limit and suggests tuning test parallelism or server capacity.
License: The repository identifies the project as MIT licensed.
Maker: The repository is maintained under the GitHub account peterldowns; the opened project page does not state a maker name, headquarters, or founding date.
