prepared statement \"s0\" already exists when connecting to pgbouncer with ssl

Bug description

I’m connecting to postgres on digital ocean with pgbouncer as guided here: https://www.prisma.io/docs/concepts/database-connectors/postgresql#configuring-an-ssl-connection. And also appended pgbouncer=true&statement_cache_size=0 as suggested by @ryands17

ConnectorError: prepared statement \"s0\" already exists when connecting to pgbouncer with ssl is thrown for every query.

Full error:

PrismaClientUnknownRequestError3 [PrismaClientUnknownRequestError]:
Invalid `prisma.siteMember.findMany()` invocation:


  Error occurred during query execution:
ConnectorError(ConnectorError { user_facing_error: None, kind: QueryError(Error { kind: Db, cause: Some(DbError { severity: "ERROR", parsed_severity: Some(Error), code: SqlState("42P05"), message: "prepared statement \"s0\" already exists", detail: None, hint: None, position: None, where_: None, schema: None, table: None, column: None, datatype: None, constraint: None, file: Some("prepare.c"), line: Some(463), routine: Some("StorePreparedStatement") }) }) })

    at runMicrotasks (<anonymous>)
    at processTicksAndRejections (internal/process/task_queues.js:97:5) {
  clientVersion: '2.13.0'
}

How to reproduce

1. Setup a managed database on digital ocean.
2. Create pgbouncer pool.
3. Connect with SSL config the above.
4. Run any query

Expected behavior

Prisma queries should be executed normally when connected to a pgbouncer pool’d db.

[AlessandroA]

It’s working for me. I use prisma/client 2.12.1 and the following DATABASE_URL:

postgresql://username:password@db_host:5432/dbname?schema=public&pgbouncer=true&sslmode=require

(note the pgbouncer and sslmode options)

[s-kris]

I was able to connect to pool with SSL. The change I did was to remove sslidentity and sslpassword from connection string. Was able connect to DO cluster using .crt file.

DATABASE_URL=postgres://XXXXXXXXXXXXXX?connection_limit=3&sslmode=require&&sslcert=ssl.crt&pgbouncer=true&connect_timeout=10&pool_timeout=30
