I think that it is good to specify the flags by one character as well
as Perl.
I propose the following specification:
regexp_replace(source text, pattern text, replacement text, [flags text])
returns text
The flags can use the following values:
g: global (replace all)
i: ignore case
When the flags is not specified, case sensitive, replace the first
instance only.
