Tom Lane eb213acfe2 Prevent duplicate escape-string warnings when using pg_stat_statements. ... contrib/pg_stat_statements will sometimes run the core lexer a second time on submitted statements. Formerly, if you had standard_conforming_strings turned off, this led to sometimes getting two copies of any warnings enabled by escape_string_warning. While this is probably no longer a big deal in the field, it's a pain for regression testing. To fix, change the lexer so it doesn't consult the escape_string_warning GUC variable directly, but looks at a copy in the core_yy_extra_type state struct. Then, pg_stat_statements can change that copy to disable warnings while it's redoing the lexing. It seemed like a good idea to make this happen for all three of the GUCs consulted by the lexer, not just escape_string_warning. There's not an immediate use-case for callers to adjust the other two AFAIK, but making it possible is easy enough and seems like good future-proofing. Arguably this is a bug fix, but there doesn't seem to be enough interest to justify a back-patch. We'd not be able to back-patch exactly as-is anyway, for fear of breaking ABI compatibility of the struct. (We could perhaps back-patch the addition of only escape_string_warning by adding it at the end of the struct, where there's currently alignment padding space.)		11 years ago
