pg_upgrade problem - Mailing list pgsql-hackers

I am updating a database from 6.4 to 6.5.  This statement was produced
by 6.4.2's pg_dumpall but is not accepted by 6.5:
 CREATE RULE "rtest_v1_upd" AS ON UPDATE TO "rtest_v1"     DO INSTEAD UPDATE rtest_t1 SET "a" = new."a", "b" = new."b"
 WHERE "a" = current."a";
 
 ERROR:  current: Table does not exist.

This rule is part of the regression tests and it seems that `current' has
now been changed to `old'.  Apart from the error messages that occur
as the script flows past (too fast to read) pg_upgrade does not
offer any explanations; it merely says that psql failed to run the
script, which is contrary to what the user (me) thinks he has just seen.

This particular problem can be fixed by applying this sed command to
the script:
 sed -e '/^CREATE RULE /s/current\./old./g'

with some smallish risk of breaking rules where some table has a name
ending in `current'.


I'm currently trying to fix the automatic upgrade procedure for Debian's
postgresql package.  Are there any other problems like this that people
might meet?




I attach a patch for pg_upgrade.  This does two things:

1. check whether the program is being executed in $PGDATA/..  This is  necessary if the data tree is not in the
standardplace, as is the  case with the Debian distribution (because of Debian policy).
 

2. give a clearer error message if the dumped data structure fails to  be loaded.
