In the course of adding a new backslash command, this patch manages to
touch:
* the main loop's concept of what types of backslash commands exist (PSQL_CMD_NOSEND ... what's the point of that,
ratherthan making this work the same as \g?)
* SendQuery's concept of how to process command results (again, why isn't this more like \g?)
* ExecQueryUsingCursor's concept of how to process command results (why? surely we don't need \gset to use a cursor)
* the psql lexer (adding a whole bunch of stuff that probably doesn't belong there)
* the core psql settings construct (to store something that is in no way a persistent setting)
Surely there is a less ugly and invasive way to do this. The fact
that the reviewer keeps finding bizarre bugs like "another backslash
command on the same line doesn't work" seems to me to be a good
indication that this is touching things it shouldn't.
