iam developing version control system based on content because i havent found anything for postgres and it sounds like great tool to have. Propably i will use Rules and Views with shadow tables, but iam interested in alternative to examine WAL files.
So iam interested in WAL file format and information that can be extracted from it. Is there any way to build some API above WAL file to be able to analyze data changes in time caused by DML ? Iam aware of xlog.c but not of its capabilities and features, its kind of hard for me to analyze that file.
MS SQL create transaction logs and there are tools like ApexSQL Log that can analyze logs a redo changes made by DML. So i thought it would by great to have such tools for opensource system like postgres.
Also, if anybody has any ideas or alternatives on content version control system i will be realy thankfull.
