Обсуждение: pgsql: Fix ancient typo in user-defined-aggregates documentation.
Fix ancient typo in user-defined-aggregates documentation. The description of the initcond value for the built-in avg(float8) aggregate has been wrong since it was written. Noted by Disc Magnet.

Maybe this should say two or three-element given the example that immediately follows it. -- Thom Brown Twitter: @darkixion IRC (freenode): dark_ixion Registered Linux user: #516935 EnterpriseDB UK: http://www.enterprisedb.com The Enterprise PostgreSQL Company

Oh, I shouldn't have done that with blinders on :-(. I think probably

average. Will fix as soon as I get back from my doctors appointment.
