What do you mean with that? You mean you'd rather see a copy in pg_xlogdump somewhere? How would you trigger that being used instead of the normal description routine? > +/* free opcode 0x70 */ > + > +#define XLOG_XACT_OPMASK 0x70 > There is a contradiction here, 0x70 is not free. The above is a mask, not an opcode - so I don't think it's a contraction. I'll expand on the commentary on the next version. Thanks for having a look!
