Release 7.4.5

Hi,

The recent Postgres7.4.5 mentions a fix for a crash.
http://www.postgresql.org/docs/7.4/static/release.html#RELEASE-7-4-5
"Repair possible crash during concurrent btree index insertions
This patch fixes a rare case in which concurrent insertions into a btree
index could result in a server panic. No permanent damage would result,
but it's still worth a re-release. The bug does not exist in pre-7.4
releases."

Is this crash anyway related to :
WARNING:  specified item offset is too large
PANIC:  failed to add item to the page for "<table_index_key>"
LOG:  server process (PID 3786) was terminated by signal 6
LOG:  terminating any other active server processes

I have been getting this crash for a while.
My app uses Postgres 7.4.3 on SunOS 5.9 Generic_112233-01 sun4u sparc
SUNW,UltraAX-i2

Is it worth to upgrade it to use 7.4.5?

Thanks,
Rajan
