I can't muster a lot of outrage about this one way or another.  One
possible advantage of 'P' is that there are fewer places where 'P' is
mentioned in the source code than 'p'.

[rhaas pgsql]$ git grep "'p'" | wc -l
[rhaas pgsql]$ git grep "'P'" | wc -l

...so it's a little easier to pick out the cases that are talking
about partitioned tables than it would be with a lower case letter.
However, as I say, I don't care very much.
