(although actually, why wouldn't we want to just implement variable substitution exactly like it is in psql?
Pgbench variable substitution is performed when the script is run, not while the file is being processed for being split, which is when a lexer would be used. The situation is not the same with psql. The most it could do would be to keep track of what substitution are done in queries.
So this is looking *eminently* doable.
Possibly. How much more effort would be involved compared to the quick patch I did, I wonder:-)
