Thread: Restoring pg_dump Backup with psql Fails
PostgreSQL 8.2.4 on RedHat ES4 64-bit
Hi all,
Doing some works on a database this morning (changing it to take data from
our new ERP system) so naturally I made a backup of the database first:
pg_dump important_database > ~/backup/important-071229.sql
chmod 440 ~/backup/important-071229.sql
Of course things have screwed up (fortunately no-one is working today) and I
need to restore:
psql
ALTER DATABASE important_database RENAME TO
important_database071229;
CREATE DATABASE important_database;
\q
psql important_database < ~/backup/important-071229.sql
But I get a whole bunch of errors, for example:
<snip>
ERROR: syntax error at or near "all"
LINE 1: all orders over $400.00 - freight free Order 10 of any produ...
^
ERROR: syntax error at or near "If"
LINE 1: If stores spend over $300.00 they will receive a 5% discount...
<snip>
invalid command \.
invalid command \.
invalid command \N
invalid command \N
<snip>
Both psql and pg_dump are the correct versions:
[postgres@stirling ~]$ ls -lh `which pg_dump`
lrwxrwxrwx 1 root root 31 Jul 25 11:51 /usr/local/bin/pg_dump ->
/usr/local/pg-8.2.4/bin/pg_dump
[postgres@stirling ~]$ ls -lh `which psql`
lrwxrwxrwx 1 root root 28 Jul 25 11:51 /usr/local/bin/psql ->
/usr/local/pg-8.2.4/bin/psql
(I compile each new version of Postgres to it's own folder and data dir:
/usr/local/pg-<version>/ and /home/Postgres/pgData-<version> )
What am I doing wrong?
Cheers,
~p

Please show us the *first* few errors, not some randomly chosen ones.
The above looks like a COPY has failed and psql has started thinking
that copy-data lines are commands, but how or why that happened is
not in evidence.

Sorry Tom - I should know better :) I've attached the first 512 lines of the output from psql. The whole output is 3mb.

Hmm, these are a bit troubling:
> ERROR: relation "grps" already exists
> ...
> ERROR: relation "stock" already exists
because you claimed you were restoring into an empty database ---
either you're mistaken or there is an interesting bug in pg_dump.
Please look into that more closely.
It's hard to be entirely certain, but the subsequent errors seem to
mostly flow from having pre-existing tables "grps" and "stock" that
don't match what the dump script is expecting.
There seems to be a separate encoding problem too:
> ERROR: invalid byte sequence for encoding "UTF8": 0x96
> HINT: This error can also happen if the byte sequence does not match the encoding expected by the server, which is
controlledby "client_encoding".
> CONTEXT: COPY dwh_cust, line 7413
> ERROR: invalid byte sequence for encoding "UTF8": 0xe86d65
> HINT: This error can also happen if the byte sequence does not match the encoding expected by the server, which is
controlledby "client_encoding".
> CONTEXT: COPY dwh_stk, line 323461
You didn't mention what PG version you are dumping from, but I'm
thinking it was one that wasn't very strict about encoding correctness.
You may need to clean up the dump file with iconv or some similar tool
--- look through the PG archives for lots of previous discussions about
that.

I think I've found my problem:
[postgres@stirling backups]$ psql template1
Welcome to psql 8.2.4, the PostgreSQL interactive terminal.
template1=# \d
List of relations
Schema | Name | Type | Owner
--------+--------------+-------+----------
public | buyers | table | postgres
public | creditors | table | postgres
public | debtors | table | postgres
public | grps | table | postgres
public | po | table | postgres
public | sales_orders | table | postgres
public | stkmvt | table | postgres
public | stock | table | postgres
public | sys | table | postgres
(9 rows)
template1=#
I don't know how or when those tables were created in template1 - they're
certainly not supposed to be there or needed. Is it safe to just DROP the
tables from template1?
> Secondly you need to look into iconv to fix your invalid UTF8 data.
My bad - the old database was using SQL_ASCII encoding, but when I recreated
it I let it default to UTF8.
Re-created it again with SQL_ASCII encoding, which didn't copy the tables
from template1 and now the restore seems to be going OK :)

Yeah, but what other user-created stuff (functions for instance) might
be in there?
You might want to drop template1 and recreate it from template0.
(There's a blow-by-blow article about doing that on techdocs, IIRC.)
