Here's a small patch against branch 8.4 to mention support for COMMENT
ON index_name.column_name.
Also, a patch against master to:
* get rid of the bogus "Description" outputs for \d+ sequence_name
and \d+ index_name
* clarify in the COMMENT ON doc page that a table _or view_ name may
be used for comments on columns, rules, and triggers. If we allowed
constraints on views, we could have just put in a note explaining that
"table_name.column_name" applies to tables and views, but constraints
are the odd man out.
* slightly reordered the listing of the first bunch of Parameters on
that page so that agg_name comes first, as it does in the Synopsis
section
I noticed that the synopsis for CREATE RULE:
http://www.postgresql.org/docs/9.1/static/sql-createrule.html
uses the term "table", which could be a similar omission. However, on
that page the first sentence of the description specifies "table or
view" so it might be fine as-is.
And while I'm messing with this, some further nitpicks about psql not
addressed by these patches:
* The "Storage" column for \d+ sequence_name is correct, I suppose,
but repetitive
* The "Type" column for \dv+ view_name, \di+ index_name, \ds+
sequence_name , etc. seems borderline useless.. shouldn't you know
what type you're looking at based on the backslash command you're
using? Plus the table heading could be more specific than "List of
relations", e.g. "List of views".
