I think you're looking for the GROUPING() function. See
http://www.postgresql.org/docs/9.5/static/functions-aggregate.html
It just dawned on me that you may note have meant having them in a
specific sequence in the result set. Even still, I think it's much more
clear being explicit with what rows are included and which aren't.

The post refers to the generic unmanageability of enums in genaral, it just
uses MySQL as a reference basis.
Google evil enum and you will find several articles that all say the same
thing.
To be specific,even in PostgreSQL, there is no easy way to delete enum
values once they exist, other than pla
Why? You're already provided with this information: NULL fields are not
being used in the grouping set for the row. Moreover, it would seem to
be an implementation- and run-time- dependent value, as there is no
reason group by grouping set (a,b), (c,d) couldn't be executed in
written order, or (c,d

This post is about MySQL's enums, which aren't really related to
Postgres enums:
"In order to change the allowed values of an enum column, we
need to issue an alter table statement [.
It would help if the resultset has some param to mark which is which with
the grouping sets index.
for example, the results for (a,b,c,d) would be marked as for index =0,
(b,c,d) would be index=1

Do you want to know if a row is from the (a,b) or (c,d) group? All rows
will contain (a,b,c,d) but (a,b) will be NULL for the (c,d) grouping
sets, and vice-versa.

Hi. Is there a way with to_char to suppress a decimal point, like a
leading or trailing 0, so that integers will not have them, but non-ints
will? I'm hoping I'm missing something easy. Thanks.

I guess that would work if you used a view to combine both tables, but you
would still need a BEFORE trigger to make sure DML goes to the appropriate
table.
Another solution might be to use dblink if you need to access the SATA
table on the 2nd VPS,

Did you initialize the DB cluster (initdb -D /path/to/data)?
Did you configure the installation (postgres.conf file)?
Does homebrew.mxcl.postgresql where the data lives?
when you run "ps -ef|grep -i postg", do you see the postmaster and other
postgres executables running?

Hello!
I am trying to move from (successfully) using VM Fusion with CentOS Linux
image on Mac OSX "El Capitan" for web development to Homebrew:
brew update
brew install postgres
brew tap homebrew/services
This resulted in some files installed to
/usr/local/Cellar/postgresql/9.5.1
