I just noticed this comment in scan.l: /* * GUC variables. This is a DIRECT violation of the warning given at the * head of gram.y, ie flex/bison code must not depend on any GUC variables; * as such, changing their values can induce very unintuitive behavior. * But we shall have to live with it as a short-term thing until the switch * to SQL-standard string syntax is complete. */ int backslash_quote = BACKSLASH_QUOTE_SAFE_ENCODING; bool escape_string_warning = true; bool standard_conforming_strings = true;
I'm not exactly sure what else needs to happen to remove these forbidden GUCs and if we are not prepared to do this now when will we ever be... David J.
