I'm writing some papers about PostgreSQL physical storage and I'm
bumping into the HeapTupleHeaderData layout as descripted here
Reading the source code in src/include/access/htup.h I got a question.
The t_cmin and t_cmax stores the insert and delete CID stamps.
the CID (command that operate on item id?) is similar to XID? where I
can find some docs about CID and its meaning?
Thank you very much in advance.
