   (<productname>PostgreSQL</productname> does this automatically when needed.)
   GiST indexes are lossy because each document is represented in the
   index by a fixed-length signature.  [-Signature-]{+The signature+} length in bytes is determined
   by the value of the optional integer parameter <literal>siglen</literal>.
   [-Default-]{+The default+} signature length (when <literal>siglen</literal> is not [-specied)-]{+specified)+} is
   124 bytes, [-maximal-]{+the maximum signature+} length is 2024 bytes. The signature is generated by hashing
   each word into a single bit in an n-bit string, with all these bits OR-ed
   together to produce an n-bit document signature.  When two words hash to
   the same bit position there will be a false match.  If all words in
   the query have matches (real or false) then the table row must be
   retrieved to see if the match is correct.  Longer signatures [-leads-]{+lead+} to {+a+} more
   precise search [-(scan less-]{+(scanning a smaller+} fraction of [-index, scan less-]{+the index and fewer+} heap
   pages), [-but-]{+at the cost of a+} larger index.
