Hi Pavel,
In xfunc.sgml, I came across a function example (for use of VARIADIC in
polymorphic functions),
where the function name is concat(): (in the manual: 35.4.10. Polymorphic
SQL Functions).
Although that is not strictly wrong
contrib/stringfunc was missing this small change in contrib/Makefile, I think.
With it, it
installs and runs make check cleanly.

Because the slave is readonly.
