Subject: Make purgehook aware of files in data/ and issue xkey purges
X-Git-Url: http://git.postgresql.org/gitweb/static/gitweb.js?a=commitdiff_plain;h=8cb19f882d72487e944d7188fdebc13a99f7e323;p=pgweb.git

Make purgehook aware of files in data/ and issue xkey purges

For any changes to files in data/, issues an xkey purge of
data_<filename_without_extension>. This allows us to automatically purge
out data based on changes to data files in the git repository.
