Description
After importing pugsql, calling sqlalchemy's has_table method causes an infinite recursive loop. This may happen when any BindParameter is used but I am not sure.
To reproduce:
-Import pugsql
-Create an MSSQL pyodbc sqlalchemy engine
-Call the dialects has_table method like this:
engine.dialect.has_table(engine, table, schema=schema)

Research direction
Start by reproducing the loop after importing pugsql with an MSSQL pyodbc SQLAlchemy engine, then call engine.dialect.has_table(engine, table, schema=schema). Trace the recursion through _visit_bindparam and determine the intended stopping point; done means has_table returns without recursing indefinitely.
