Module dependencies 

Traverse stored expressions and recognize their column dependencies.

Modules

oid_alias

Read OID alias constants at analysis as the reg* input functions read them: a regclass, regtype, regproc, regprocedure or regnamespace cast of a string literal, or a cast to an array of one of them, stores the OIDs the names resolve to, as parse analysis stores the constant, so a stored expression follows the objects through renames and a name no object has is reported where the expression is analyzed.

regclass

Bind literal relation references in persisted SQL schema expressions to the relations they name when the expressions are published or loaded. Analysis reads them earlier, in oid_alias.

registration

Bind and rewrite durable routine identities in stored SQL schema expressions.

rewrites

Rewrite stored relation, column, and literal sequence references in SQL schema expressions.

Functions
