I know it is in the docs, but right now I can't see it.
How do I pull the length of a specific varchar column? I have just found a problem with our schema being out of sync on one specific column, and need to find out how many of our 200+ databases need to be fixed.
Here is what I have so far:
select *
from pg_class, pg_attribute
where pg_class.relkind = 'r' and
pg_attribute.attrelid = pg_class.oid and
pg_class.relname = 'mytable' and
pg_attribute.attname = 'problem_column' and
???? != 256; -- need to report anytime this column is not a varchar(256).
Thanks,
Chris
