Postgres - ERROR: prepared statement “S_1” already exists

Question

When executing batch queries via JDBC to pgbouncer, I get the following error:

org.postgresql.util.PSQLException: ERROR: prepared statement \"S_1\" already e         


        

Answer 1

I had this problem, we have pgbouncer configurated in transaction level, we were using psql 11.8, we just upgraded the psql jar to the latest version, it got fixed.
