Hi Rusty,
In which case can you not include the text around the schema & table creation commands to ensure other instances of
"public"do not match the string?
I'm not sure exactly what the pg_dump output contains, but you could use something like:
cat pg_dump.sql | sed 's/CREATE SCHEMA "public"/CREATE SCHEMA "new_schema"/' | \
sed 's/CREATE TABLE "public"./CREATE TABLE "new_schema"./' > new_schema.sql
This should avoid any ambiguity as to which instances of "public" you want changed in the pg_dump sql file.
I think adding support for changing schema names in pg_dump would make it unnecessarily complex, as why just schemas?
Alsorename databases, tables, columns, index names, change comments...
I've yet to find something like this I couldn't do with sed, & if there was there is always awk for the truly desparate
:-)
pg_dump generates the dump, reliably, simply & safely. Any change you want from the original is not, IMHO, the role of
abackup program. That should ONLY back up a replica of your data. Make changes afterwards if you like, but a backup
programshouldn't modify your data.
Just my 02c, & I ain't no Postgres developer, so I'm not speaking for them in this....

Hi Brent,
It's not he best solution, because we could have fields containing
"public" in their names and sed would happily change those to test1 as
well.
I'm looking for a safer solution, thats why it should be a part of
pg_dump.
