Then why shouldn't I use strncmp() for all comparisons?
I have no idea :-) -- because it's not locale-aware perhaps.
Could someone who does have an idea answer these questions:
* Does it need to be locale-aware or not?
* Should I use strncmp() or varstr_cmp() to compare strings?
* Shouldn't it use one or the other, but not both?
Sorry, I'm just confused about the "correct" thing to do here. If
someone who knows the definitive answers could weigh in, I'd be happy to
make the adjustment.
I'm sorry. I meant bttext()
http://doxygen.postgresql.org/varlena_8c-source.html#l01270
bttext should use in citextcmp function. It uses strcol function.
And citext_eq should be implemented as texteq:
http://doxygen.postgresql.org/varlena_8c-source.html#l01164
I'm sorry for confusion I'm exchange bttext and varstr_cmp. :(
