Subject: What do these terms mean in the SOURCE CODE?
To: pgsql-hackers(at)postgresql(dot)org
I am going through the Executor code and come across the following terms
quite often. Can someone tell me what do they mean (in a few (may be a
couple of) sentences)?
1. Scan State
2. Plan State
3. Tuple Projection
4. EState
5. Qual
6. Expression
They sound quite ambiguous in the source code, specially when some of them
already have terms which have multiple meanings.
Thanks for your time.
