Where is the qualification par in the Query Tree

2020-04-21 Thread Marc Rechté
This refers to /doc/src/sgml/html/querytree.html, where one mentions a qualification part in the Query Tree. While reading the Query node (parsenode.h) and output from the log with debug_print_parse = on, I cannot see either this part. Is it gone in profit of join tree ?

Hello, Don't know if this the correct list to submit this issue. On the https://www.postgresql.org/developer/backend/, it mentions a Query.qual field which does not exist in the Query structure. Thanks
