while adding a column to an existing system catalog I am getting following
error while initdb
FATAL: incorrect number of columns in row (expected 22, got 21)
where do I have to make the changes ?
My doubt is what changes does one have to make in the source code if he/she
is trying to add an attribute to the existing system catalogs table ?
We are trying add columnar support to postgreSQL and for that we need
identify each column in each relation by an oid. So my doubt is how do we
add an attribute/ a column to catalog pg_attribute ?
I want to add a column to system catalog pg_attribute for getting an oid
for a column also. How do we add a column into pg_attribute ?
My doubt is when the query enters into a portal, does it stay in the portal
till the final execution ? i.e. Do the further function calls such as
DefineRelation,create_heap_with_catalog etc. for Create query occur inside
the portal ?
