Just to make sure I understand this correct : > You can write PostgreSQL extension in C - and store XML only in memory.Meaning that I write function(s) which processes the XML using C which will allow me more option with processing theXML ? Will this allow me to cache the payload data in memory for the connection and not only for a single function ? Ifnot , this approach will not work , unless I rewrite a lot of the code / functions. The current solution makes use of aseparate function for each different part of the XML. Reason for this is that a lot of validation is also done on the data.> Temp tables are best when you do some queries or when you need indexes, but > it is terrible slow cache. >> else - Postgres is good as database and very slow as cache.

I'll then try to replace the temp tables with actual tables with some kind of UID.
