Обсуждение: Query to check Progress of Alter Statements PostgreSQL

Is there a system table to query the progress of Alter Statements like Type Modification and Key Creation in PostgreSQL?

1. alter table seqentry1 alter column "timestamp" type text USING "timestamp"::text;
2. ALTER TABLE ONLY public.seqentry2 ADD CONSTRAINT fk_seq2 FOREIGN KEY (seq_id) REFERENCES public.seqshow(seq_id);
