introspect

Overview ¶

Package introspect reads the live schema of a database into the same structures codegen builds from the Go models, so the two can be compared.

drel's migration differ works from a snapshot of what drel itself generated. A constraint or an index written by hand is absent from that snapshot, so every later migration is planned as though it did not exist. Introspection makes such an object visible: `drel migrate verify` reports it.
