Here's an interesting one for you...
psql (9.6.7, server 11.3) on linux
I have 2 DBs, differnet servers/instances. I want to take all the
metadata and data for a set of tables/views in the public schema of one
DB and move it all over to be inside a schema of a second DB/instance.
Well first, the current minor version of 9.6 is .17 so you are 10
releases behind. In fact the 9.6.8 release includes changes that impact
the below:
https://www.postgresql.org/docs/9.6/release-9-6-8.html
I'm using pg_dump to create the script and I believe I can insert a "set
search_path=myschem" in the output of pg_dump such that when it runs,
the "CREATE TABLE", "CREATE VIEW", "GRANT...", etc.... commands, will
all go into the new schema (which I have prepared). Problem is the view
defs.
The view defs do not prefix the referenced tables with "myschem.", so
the CREATE VIEW xyx commands fail.
Is there a way to do this ?
By manually changing the definition? It is not an error for a VIEW in
one schema to refer to tables in other schemas. AFAIK the code has no
way of knowing you want to move the underlying tables just by specifying
a search_path.
Thanks in Advance.
