Description
If the database receives a reconnect request for a session that is currently executing a metadata query (e.g. in ODBC SQLPrimaryKeys() or in JDBC getColumns()), other sessions that run metadata queries may hang.
Workaround
A restart of the database is required to enable metadata query execution again.
Fix
Sessions which send a reconnect during metadata query execution will no longer cause other sessions' metadata queries to hang.
