4920 don't necessarily need to follow all the rules exactly, such as requiring
4921 that the first character not be a digit.
4923 We allow leading and trailing white space. In between, we do not allow
4924 punctuation (except for underscores and dollar signs), control
4925 characters, or embedded white space.

4945 // (as in schema.identifier), control characters and other
4946 // punctuation characters are not okay. Anything else
4947 // is okay -- it could for example be part of a multibyte
4948 // UTF8 character such as a letter with diacritical marks,

4975 Determine whether to accept a character string as a comparison operator.
4976 Return 1 if it's good, or 0 if it's bad.
4978 We don't validate it for real. We just make sure that it doesn't contain
4979 any semicolons or white space (with a special exception for the
4980 "SIMILAR TO" operator). The idea is to block certain kinds of SQL
4981 injection. If it has no semicolons or white space but it's still not a
4982 valid operator, then the database will complain.
4984 Another approach would be to compare the string against a short list of
4985 approved operators. We don't do that because we want to allow custom
4986 operators like ">100*", which would be difficult or impossible to
4987 express otherwise in a JSON query.
