hi.

in doc/src/sgml/func/func-matching.sgml

<synopsis>
substring(<replaceable>string</replaceable> similar
<replaceable>pattern</replaceable> escape
<replaceable>escape-character</replaceable>)
</synopsis>
     or using the now obsolete SQL:1999 syntax:
<synopsis>
substring(<replaceable>string</replaceable> from
<replaceable>pattern</replaceable> for
<replaceable>escape-character</replaceable>)
</synopsis>
     or as a plain three-argument function:
<synopsis>
substring(<replaceable>string</replaceable>,
<replaceable>pattern</replaceable>,
<replaceable>escape-character</replaceable>)
</synopsis>

key word: "similar", "escape", "from", "for" within the above synopsis
section need uppercase too?

I don't think that would be a good change.  substring is also a keyword, 
but it was said not to upper-case keywords used as functions.  So in my 
mind that should also apply to other syntax elements of function-like calls.
