Hi, I'm writing some papers about PostgreSQL physical storage and I'm bumping into the HeapTupleHeaderData layout as descripted here http://www.postgresql.org/docs/8.2/static/storage-page-layout.html
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.
