* fix database existence check follow up to #372 * always dispose engine after db existence check * add docs for postgres_db parameter * fix dialect_name Co-authored-by: Nicola Soranzo <nicola.soranzo@gmail.com> * optimize execution order Co-authored-by: Nicola Soranzo <nicola.soranzo@gmail.com> * database_exists fix return - postgres: return for the first positive test - use immutable for default argument * use None as default Co-authored-by: Nicola Soranzo <nicola.soranzo@gmail.com> * break if successful Co-authored-by: Nicola Soranzo <nicola.soranzo@gmail.com> * dispose only for exception * use Null connection pool and close connections - use a connection (which is closed automatically) for data base existence check - explicitely use Null connection pool already with the 1st change disposal of the engine (which closes all open connections) is not necessary anymore. with the second change we are completely sure. * fix isort call in tox.ini and import order * rename parameter to databases * move functions to module level * Add support for SQLAlchemy 1.4 Import _ColumnEntity from sqlalchemy.orm.context if importing from .query fails. And while checking if database_exists, use url.set() as URL object is now immutable. * Fixed errors related to URL.database not being directly settable. * Removed the try..except constructs to set the database. Now checking *once* the version of sqlalchemy in use and deciding *once* how to change the database address. Using a wrapping function ('set_database_from_url') to simplify the code. * Cleanups * Use `execution_options()` method of `Connection` to set the transaction isolation level to autocommit for PostgreSQL. * Lint fixes * Move CI lint job to GitHub workflows * Testing: drop Python 3.5 and Python 3.9 * Use `with engine.connect()` context manager Consolidate autocommit across drivers that support it, xref. #494 and fix #486 . * Move CI tests from TravisCI to GitHub workflows * Add SQLAlchemy 1.3 on Python 3.6 to the test matrix * Update tests for changes in `create_database` to use `with engine.connect()` context manager (commit 4f52578 ) * Install the version of pg8000 recommended by SQLAlchemy 1.3 when testing. xref. #500 Fix the following exception: ```

* fix database existence check follow up to kvesteri#372 * always dispose engine after db existence check * add docs for postgres_db parameter * fix dialect_name Co-authored-by: Nicola Soranzo <nicola.soranzo@gmail.com> * optimize execution order Co-authored-by: Nicola Soranzo <nicola.soranzo@gmail.com> * database_exists fix return - postgres: return for the first positive test - use immutable for default argument * use None as default Co-authored-by: Nicola Soranzo <nicola.soranzo@gmail.com> * break if successful Co-authored-by: Nicola Soranzo <nicola.soranzo@gmail.com> * dispose only for exception * use Null connection pool and close connections - use a connection (which is closed automatically) for data base existence check - explicitely use Null connection pool already with the 1st change disposal of the engine (which closes all open connections) is not necessary anymore. with the second change we are completely sure. * fix isort call in tox.ini and import order * rename parameter to databases * move functions to module level * Add support for SQLAlchemy 1.4 Import _ColumnEntity from sqlalchemy.orm.context if importing from .query fails. And while checking if database_exists, use url.set() as URL object is now immutable. * Fixed errors related to URL.database not being directly settable. * Removed the try..except constructs to set the database. Now checking *once* the version of sqlalchemy in use and deciding *once* how to change the database address. Using a wrapping function ('set_database_from_url') to simplify the code. * Cleanups * Use `execution_options()` method of `Connection` to set the transaction isolation level to autocommit for PostgreSQL. * Lint fixes * Move CI lint job to GitHub workflows * Testing: drop Python 3.5 and Python 3.9 * Use `with engine.connect()` context manager Consolidate autocommit across drivers that support it, xref. kvesteri#494 and fix kvesteri#486 . * Move CI tests from TravisCI to GitHub workflows * Add SQLAlchemy 1.3 on Python 3.6 to the test matrix * Update tests for changes in `create_database` to use `with engine.connect()` context manager (commit 4f52578 ) * Install the version of pg8000 recommended by SQLAlchemy 1.3 when testing. xref. kvesteri#500 Fix the following
