Struct DbState 

pub struct DbState {
    pub schemas: Vec<String>,
    pub tables: Vec<DbTable>,
    pub enums: Vec<DbEnum>,
    pub domains: Vec<DbDomain>,
    pub sequences: Vec<DbSequence>,
    pub views: Vec<DbView>,

    pub extensions: Vec<String>,
}

Snapshot of the live PostgreSQL database, built by Python from pg_catalog queries.

Fields

schemas: Vec<String>

User-managed schema names (excludes pylon, public, pg* etc.).

tables: Vec<DbTable>

enums: Vec<DbEnum>

domains: Vec<DbDomain>

sequences: Vec<DbSequence>

views: Vec<DbView>

functions: Vec<DbFunction>

extensions: Vec<String>

Installed Postgres extension names (e.g. vector) — used to decide whether a CREATE EXTENSION needs to be added to a migration; see required_extensions/missing_extension_ddl.
