Re: pg_dump not appending sequence to default values

Yes, that's true - it's in the search path because (so I believe)
pg_dump is adding a "SET search_path..." line before it carries out the
commands in the schema, which works when the dump is restored, but when
running as a normal user, the search path is the default ($user, public)
and tax_id doesn't exist in the public schema (it exists as
product.tax_id.)  As I said a work-around is to set the user's
search_path to include all schemas.

Nope.  I actually took the dump as I was writing the e-mail and verified
that what I was saying was correct.  The pg_dump command I used to
create it was:

pg_dump.exe --host=localhost --port=5432 --username=pgsql
--file="C:\SVN\Aspire Platform\_developer\Platform Database.sql"
--schema-only --format=p aspire_platform

The default expression to begin with was "nextval('product.tax_id')" -
either PostgreSQL or the GUI application converted it to
"nextval('product.tax_id'::regclass)".  When pg_dump dumps it out, it
adds the "SET search_path = product, public" line and strips off the schema.

Forgive me if I have made any assumptions, but I cannot see where I can
break it.  The client application reports it as including the schema
name in the nextval() clause, then after pg_dump has "dumped" it, within
the SQL file it's gone and been replaced with a "SET search_path..."
clause.  When this SQL dump is restored, the schema is missing from the
nextval() clause because of the "SET search_path" that pg_dump set.

I don't know where else it can go wrong, unless there's some other
switch I should be passing to pg_dump?

PS.

Interestingly, pg_dump seems to be inconsistent in when it writes out
schemas - this block of lines are right next to each other (and after
the SET search_path line.)  Notice how it's not qualified the first 3
lines, but the 4th it has?

ALTER TABLE ONLY tax ALTER COLUMN id SET STATISTICS 0;
ALTER TABLE ONLY tax ALTER COLUMN band_name SET STATISTICS 0;
ALTER TABLE ONLY tax ALTER COLUMN tax_rate SET STATISTICS 0;

ALTER TABLE product.tax OWNER TO my_user;
