Hi hackers,
I used jdbc to connect to PostgreSQL ,and I found parse
nearly three
times of bind and execute.Is is normaly?
Actually bind and execute should be more than parse. Have you
confirmed that by enabling Log/Debug messages on server or you are
referring to JDBC log?
Thanks for your reply.
This is the Log/Debug messages.
Some configuration options are as follows:
log_min_duration_statement = 0'
log_statement = 'all'
log_line_prefix = '%t [%p]: [%l-1] db=%d,user=%u [%x]'
logging_collector = on
What factors may cause this result?
I am really not sure of JDBC, but from Libpq or general concept wise,
it can happen only if someone does call parse multiple times, but
then
execute only few of the statements.
I do agree with you. But I don't know what query can call parse
multiple times.
Could you give me more information or example about this case？
