Minor mistake in string functions docs - overlay

I found a minor mistake in the documentation of string functions.

http://www.postgresql.org/docs/9.4/static/functions-string.html

In table 9-6 examples and results columns, look at the overlay function,
which has 4 x characters, but overlays 3 characters. Please remove an x.

overlay('T*xxxx*as' placing 'hom' from 2 for 4) Thomas

Please change the call to { *overlay('Txxxas'* ... }

Have a good day, and thanks for creating such amazing documentation.
