Hi,

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.

Thanks Milos
