Support for AWS Aurora DSQL: pg_try_advisory_lock not available #3539

Description

@iamralch

We are currently using AWS Aurora DSQL for PostgreSQL, a variant of Aurora that leverages a distributed query engine.

However, Aurora DSQL does not support the pg_try_advisory_lock function, which is used by Atlas to implement database-level locking during migration execution. As a result, migration attempts fail at the locking stage, preventing schema changes from being applied.

This limitation appears to be due to Aurora DSQL not yet implementing the advisory lock functions that are available in standard PostgreSQL. This is a blocker for using Atlas with Aurora DSQL out of the box.
