Hi All,
Is there any way to print / get the memory consumption taken by sql in
postgresql 9.x ? Can we also get/print the data size returned by Sql ?
There is no parameters in log_line_prefix in postgresql.conf
Please guide.

Hello,
explain (buffers, analyze) your sql statements .......
data size ???
You can put your data in a table, and check its size.
I don't what you want to check ??
buffer usages, intermediate temp object size or sorting size or some
other thing ??
You can also try pg_stat_statements contrib module for your intending
analysis.
