-  The <filename>pg_surgery</filename> module provides various functions to
-  perform surgery on a damaged relation. These functions are unsafe by design
-  and using them may corrupt (or further corrupt) your database. For example,
-  these functions can easily be used to make a table inconsistent with its
-  own indexes, to cause <literal>UNIQUE</literal> or
-  <literal>FOREIGN KEY</literal> constraint violations, or even to make
-  tuples visible which, when read, will cause a database server crash.
-  They should be used with great caution and only as a last resort.
