Hi, All!
I have problems.
There are a few tables with an established mode tabulared bufferisation (5 types). It is necessary to carry out SQL on them with inclusion in him of all changes (before updating the tables). But SQL does not see made changes!

It is possible to do initial selection of data by a command COPY TO, which sees all changes. But can there is the way easier and main faster (that not strongly braked SQL)?

Beforehand, is grateful for the answer.
