Hi, I have two questions about the documentation.
1. In section "44.3 The Parser Stage", it is said that the file scan.l is
responsible for recognizing SQL keywords... however, I downloaded the
Postgres source and it seems like all the SQL keywords are in the file
gram.y, is this correct?
Link to what I'm saying:
http://www.postgresql.org/docs/9.2/interactive/parser-stage.html
2. In section "44.5. Planner/Optimizer", it is said that the planner works
internally with *paths* and only after the shortest *path* is determined
a *plan tree* is created. Shouldn't the following section "44.5.1
Generating Possible Plans" be called "44.5.1 Generating Possible Paths"?

Thanks in advance,
