Create Index Statement

This represents creation of an index and/or an associated constraint. If isconstraint is true, we should create a pg_constraint entry along with the index. But if indexOid isn't InvalidOid, we are not creating an index, just a UNIQUE/PKEY constraint using an existing index. isconstraint must always be true in this case, and the fields describing the index properties are empty.

Fields

type_: NodeTag

idxname: *mut c_char

relation: *mut RangeVar

name of new index, or NULL for default

accessMethod: *mut c_char

relation to build index on

tableSpace: *mut c_char

name of access method (eg. btree)

indexParams: *mut List

tablespace, or NULL for default

indexIncludingParams: *mut List

columns to index: a list of IndexElem

options: *mut List

additional columns to index: a list of IndexElem

whereClause: *mut Node

WITH clause options: a list of DefElem

excludeOpNames: *mut List

qualification (partialindex predicate)

idxcomment: *mut c_char

exclusion operator names, or NIL if none

indexOid: Oid

comment to apply to index, or NULL

oldNode: Oid

OID of an existing index, if any

unique: bool

relfilenode of existing storage, if any

primary: bool

is index unique?

isconstraint: bool

is index a primary key?

deferrable: bool

is it for a pkey/unique constraint?

initdeferred: bool

is the constraint DEFERRABLE?

transformed: bool

is the constraint INITIALLY DEFERRED?

concurrent: bool

true when transformIndexStmt is finished

if_not_exists: bool

should this be a concurrent index build?

reset_default_tblspc: bool

just do nothing if index already exists?
