Tom Lane 3c9d398484 Doc: improve index entry for "median".
We had an index entry for "median" attached to the percentile_cont function
entry, which was pretty useless because a person following the link would
never realize that that function was the one they were being hinted to use.

Instead, make the index entry point at the example in syntax-aggregates,
and add a <seealso> link to "percentile".

Also, since that example explicitly claims to be calculating the median,
make it use percentile_cont not percentile_disc.  This makes no difference
in terms of the larger goals of that section, but so far as I can find,
nearly everyone thinks that "median" means the continuous not discrete
calculation.

Per gripe from Steven Winfield.  Back-patch to 9.4 where we introduced
percentile_cont.
