Re: pg_upgrade error

Hi Bruce,

On another cluster, I fixed the old cluster tablespace location by running bellow statement.

update pg_tablespace set spclocation='/opt/symcor-foa/data/pg_tblspc/federator' where spcname='federator';
select * from pg_tablespace

, but it still fails with same error. There is no symlink in this cluster.

/opt/symcor-foa/data/pg_tblspc/federator/PG_9.0_201008051/17055/11838
linking "/opt/symcor-foa/data/pg_tblspc/federator/PG_9.0_201008051/17055/11838" to "/opt/symcor-foa/data/pg_tblspc/federator/PG_9.4_201409291/16423/13013"
error while creating link for relation "pg_catalog.pg_largeobject" ("/opt/symcor-foa/data/pg_tblspc/federator/PG_9.0_201008051/17055/11838" to "/opt/symcor-foa/data/pg_tblspc/federator/PG_9.4_201409291/16423/13013"): No such file or directory

Thanks,
Yogi

My guess is that you have a mismatch between the symbolic links used in data/pg_tblspc/ and pg_tablespace.spclocation.
pg_tablespace.spclocation. was removed in Postgres 9.2, but in older releases you could have moved the tablespace without updating that field, causing pg_upgrade failures.
