Looks like these were missing from the example dovecot-sql.conf.ext:

#     connect_timeout        - Connect timeout in seconds (default: 5)
#     read_timeout           - Read timeout in seconds (default: 30)
#     write_timeout          - Write timeout in seconds (default: 30)

So e.g.:

connect = ... connect_timeout=30
