I'm afraid not. There is arbitrary limit (named NAMEDATALEN) in lexer.
If identifier exeeds it, it gets '\0' at that limit, so truncated
effectively. Strings are also limited by MAX_PARSE_BUFFER which is
finally something like QUERY_BUF_SIZE = 8k*2.
Seems that string literals are the primary target, because it is
real-life constraint here now. This is not the case with supposed
huge identifiers. Should I work on it, or will you do it yourself?
