I wasn't following this thread, but I noticed a few small potential
improvements when I saw the commit.
First, as noted in the test, it doesn't preserve the case of the input
for keywords appended to the query result. This is easily fixed by
using `pg_strdup_keyword_case()`, per the first attached patch.
The second might be more of a matter of style or opinion, but I noticed
a bunch of `if (foo) free(foo);`, which is redundant given that
`free(NULL)` is a no-op. To simplify the code further, I also made
`escape_string(NULL)` be a no-op, returning `NULL`.
