Hi All, I was able to follow the debugging of the child process using this link, https://wiki.postgresql.org/wiki/Working_with_Eclipse
As per the notes , I was able to set breakpoints and everything seem to be working (hopefully). However I am not able to see the debug messages in the eclipse console (for the attached process) . Please help When I check on the console in eclipse , this is the last message I see. 0x00007ffff73fad48 in poll () from /lib/x86_64-linux-gnu/libc.so.6 I added a 2 lines in pl_exec.c and kept breakpoints for these lines. The breakpoints work fine but I am not able to see the console log. I was able to use the log message "ereport(LOG, (errmsg("test here started")));" in autovaccum.c line 414 and see the message in the console. But this message is from the main process. I am having trouble seeing the console log only for the attached process. pl_exec.c : Line 310 : ereport(LOG, (errmsg("test here started"))); Line 311 : elog(ERROR,"test here"); Thanks Praveen
