That error indicates that the filesystem ran out of disk space.

That is incorrect. In PostgreSQL, a "tablespace" is a directory. Every
table in PostgreSQL consists of a set of files. None of the individual
files for a PostgreSQL table will be larger than 1G, but PostgreSQL will
use multiple files when it reaches 1G in size.
In the above case, the table/index with relfilenode 55041 in the
database with oid 16385 has grown to be over 5G in size. The files:
55041
55041.1
55041.2
55041.3
55041.4
55041.5
are all associated with that table/index.
Thanks!
Stephen
