Query to check Progress of Alter Statements PostgreSQL

Hi,

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);

Thanks,
Raj Kumar
