The lower the number the more severe it is.

Short Description
pg_dump crash on linux-xfs

Long Description
pg_dump crashes with PostgreSQL 7.3(1) server installed on Linux-2.4.20(2.4.19) with XFS patches from ftp://oss.sgi.com/projects/xfs/download/patches/2.4.20/xfs-2.4.20-all-i386.bz2 (and earlier patches) with ACLs and DMAPI enabled when pg_dump is used with compression enabled:

[linux-xfs-host]$ pg_dump db -Fc -f dump
Segmentation fault (core dumped)

[linux-no-xfs-host]$ pg_dump -h linux-xfs-host db -Fc -f dump
Segmentation fault (core dumped)

...and dump file contains only structure, no data.

I tried moving database from XFS to reiser partition and it still crashes.

Running pg_dump with database on server that's running vanilla 2.4.20 doesn't crash.
[linux-no-xfs-host]$ pg_dump db2 -Fc -f dump2
works fine.

PostgreSQL 7.2.x works fine.
