We're looking to deploy a bunch of new machines.
Our DB is fairly small and write-intensive. Most of the disk

We are doing Master/Standby setup, We unplugged the master server, then the

While converting the old master to new slave server, We are getting the

Hi list, (newbie with databases)
I was looking out in net about how can we determine or find all functional
dependencies in a relational database, but didn't find.
So can please anyone here tell me if functional

I guess you could call Highpoint a RAID manufacturer, but I wouldn't do so.
They've released so many terrible problems over the years that it's hard to

The only way to feed another relation into a function is to place the

Hello,
I need to search a table to find sets of rows that have a column
matching itself for the whole set and another column matching row for
row with a list I am going to supply. The result I should receive should
be value of the column that matches itself.
For example given the following
Untested approach
Use array_agg on column 2 along with group by on column 1 to build check arrays
and then use equals to compare with an array of your desired input values.
You should omit duplicates and order ascending both the data and the input to
ensure you are matching canonical forms.
An alternative approach would be to select using a IN condition on the where
clause and group by column 1 and column 2. Then, using this as a sub-select
group by the resultant column 1 and a count on column two. The matching
identifiers are those with a count equal to the number of entries in

I have a table that will be updated frequently. Each row will be
