1. createPostgresqlPoolModifiedWithVersion :: (MonadUnliftIO m, MonadLoggerIO m) => (Connection -> IO (Maybe Double)) -> (Connection -> IO ()) -> ConnectionString -> Int -> m (Pool SqlBackend)

   persistent-postgresql	Database.Persist.Postgresql

   Same as other similarly-named functions in this module, but takes callbacks for obtaining the server version (to work around an Amazon Redshift bug) and connection-specific tweaking (to change the schema).

2. createPostgresqlPoolTailored :: (MonadUnliftIO m, MonadLoggerIO m) => ((Connection -> IO ()) -> (Connection -> IO (NonEmpty Word)) -> ((Connection -> SqlBackend) -> Connection -> SqlBackend) -> ConnectionString -> LogFunc -> IO SqlBackend) -> (Connection -> IO (Maybe Double)) -> (Connection -> IO ()) -> ConnectionString -> Int -> m (Pool SqlBackend)

   persistent-postgresql	Database.Persist.Postgresql

   Same as createPostgresqlPoolModifiedWithVersion, but takes a custom connection-creation function. The only time you should reach for this function is if you need to write custom logic for creating a connection to the database.

3. createPostgresqlPoolWithConf :: (MonadUnliftIO m, MonadLoggerIO m) => PostgresConf -> PostgresConfHooks -> m (Pool SqlBackend)

   persistent-postgresql	Database.Persist.Postgresql

   Same as createPostgresqlPool, but can be configured with PostgresConf and PostgresConfHooks.

4. createRawPostgresqlPool :: (MonadUnliftIO m, MonadLoggerIO m) => ConnectionString -> Int -> m (Pool (RawPostgresql SqlBackend))

   persistent-postgresql	Database.Persist.Postgresql

   Create a PostgreSQL connection pool which also exposes the raw connection. The raw counterpart to createPostgresqlPool.

5. createRawPostgresqlPoolModified :: (MonadUnliftIO m, MonadLoggerIO m) => (Connection -> IO ()) -> ConnectionString -> Int -> m (Pool (RawPostgresql SqlBackend))

   persistent-postgresql	Database.Persist.Postgresql

   The raw counterpart to createPostgresqlPoolModified.

6. createRawPostgresqlPoolModifiedWithVersion :: (MonadUnliftIO m, MonadLoggerIO m) => (Connection -> IO (Maybe Double)) -> (Connection -> IO ()) -> ConnectionString -> Int -> m (Pool (RawPostgresql SqlBackend))

   persistent-postgresql	Database.Persist.Postgresql

   The raw counterpart to createPostgresqlPoolModifiedWithVersion.

7. createRawPostgresqlPoolWithConf :: (MonadUnliftIO m, MonadLoggerIO m) => PostgresConf -> PostgresConfHooks -> m (Pool (RawPostgresql SqlBackend))

   persistent-postgresql	Database.Persist.Postgresql

   The raw counterpart to createPostgresqlPoolWithConf.

8. defaultPostgresConfHooks :: PostgresConfHooks

   persistent-postgresql	Database.Persist.Postgresql

   Default settings for PostgresConfHooks. See the individual fields of PostgresConfHooks for the default values.

9. rawPostgresqlConnection :: RawPostgresql backend -> Connection

   persistent-postgresql	Database.Persist.Postgresql

   The underlying Connection

10. withPostgresqlConn :: (MonadUnliftIO m, MonadLoggerIO m) => ConnectionString -> (SqlBackend -> m a) -> m a

    persistent-postgresql	Database.Persist.Postgresql

    Same as withPostgresqlPool, but instead of opening a pool of connections, only one connection is opened. The provided action should use runSqlConn and *not* runReaderT because the former brackets the database action with transaction begin/commit.
