 Hi,

 http://www.postgresql.org/docs/9.1/interactive/catalog-pg-statistic.html

 It specifies that entries are created by ANALYZE, but does not mention
 that if a table is empty the entry for it is not created.

The actual behavior, in somewhat more detail, is that the existing
statistics entries, if any, are retained.

I've added a note to that effect to the documentation for ANALYZE,
which seems like a more appropriate place than the pg_statistic
documentation.
