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

Disabling prepared statements in JDBC. The proper way to do it for JDBC is adding "prepareThreshold=0" parameter to connect string.

jdbc:postgresql://ip:port/db_name?prepareThreshold=0
