"11825657and" is not any more lexically ambiguous than "11825657+".
It has to be two separate tokens, and that's how it's read.

But it's not read correctly. In other words:

delete from "ExternalDocument" where id = 11825657and "Billed" = 'f';

deleted 0 rows, while:

delete from "ExternalDocument" where id = 11825657 and "Billed" = 'f';

deleted 1 row.

[ shrug... ]  Works for me.  You want to put together a self-contained
test case showing differently?
