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.

Really? The example works as stated for me:
regression=# select overlay('Txxxxas' placing 'hom' from 2 for 4);
overlay
---------
Thomas
(1 row)
Removing an 'x' would give
regression=# select overlay('Txxxas' placing 'hom' from 2 for 4);
overlay
---------
Thoms
(1 row)
I think the example is trying to point out that the replacement string
need not be the same length as what is replaced.
