Hi,everybody recently, I found some slow SQL runtime as long as 4 seconds in postgres log. However, when I was executing on PSQL client, it takes only 3.6 milliseconds, I did the following things.
1. add auto_explain
session_preload_libraries = 'auto_explain'
auto_explain.log_min_duration = 100
auto_explain.log_analyze = true
auto_explain.log_buffers = true
2. set lock debug
log_lock_waits = on
deadlock_timeout = 500ms
log_min_duration_statement = 100
Then i find it takes only 2 milliseconds(auto_explain),but in postgres log it takes 4 seconds, please help me find this problem!!!
