developingversion control system based on content because i havent found anything for postgres and it sounds like great
toolto have. Propably i will use Rules and Views with shadow tables, but iam interested in alternative to examine WAL
files.<br/><br /> So iam interested in WAL file format and information that can be extracted from it. Is there any way
tobuild some API above WAL file to be able to analyze data changes in time caused by DML ? Iam aware of xlog.c but not
ofits capabilities and features, its kind of hard for me to analyze that file.<br /><br /> MS SQL create transaction
logsand there are tools like ApexSQL Log that can analyze logs a redo changes made by DML. So i thought it would by
greatto have such tools for opensource system like postgres.<br /><br /> Also, if anybody has any ideas or alternatives
oncontent version control system i will be realy thankfull.<br /><br /> Thanks Milos<br /><font color="#888888"><br />
