Обсуждение: PC color icon data?

Howdy:

Running PostgreSQL 7.2.1 on RedHat Linux 7.2.

I know this will sound stupid, but can someone
tell me what this means: 'PC color icon data' ?

Background: I copy a table out to a .txt file
by doing this:

[snip]
psql -U postgres -d bcn -c "\\copy measures to
'/tmp/fiveyears.txt' using delimiters '\|'"
[/snip]

and when I use it elsewhere or if I type 'file' to
make sure it's a text file, I get this:

[snip message]

[admin@localserver test]$ file fiveyears.txt
fiveyears.txt: PC color icon data

[/snip message]

I am looking at the owner of this data and I see
a pattern, but I've never heard of something like
this.  So, my *real* question should be:

How does PostgreSQL figure out what the difference
when copying a file?  I have things like "ASCII text",
"ASCII C++ program text", "Netpbm PBM image text",
"Non-ISO extended-ASCII English text, with LF,
NEL line terminators", etc ... and can I convert
them to just ASCII?

Thanks!

It doesn't. 'file' does. The data you export just happens to
look like the formats 'file' thinks it is in. And maybe it is.
Have you tried actually *looking* at the data in question ?

--yes, i've looked at it.  it appears fine.
--i just can't do a lot with it because
--i am getting errors like 'trailing null missing'
--and the like.

--i'm going to try to use MS Access or something to
--move the data around.  even when i 'cp' / 'cat' /
--'cut and paste' the data, 'file' gives me the same
--message.

--what i don't get (and this could be a Unix question)
--is why there are differences anyway.  it would
--seem to me that if the data is being copied
--out the same way, from the same location, the
--results should be the same.

--i would't think that 'file' would see different
--formats when the source should be the same.
