Обсуждение: postgresql 8.1.5 psql -P recordsep='\n' not work

Hello All.



I want to output result of query with double newline record separated.

For example:

psql -At -P recordsep="\n\n" -U postgres -c "select generate_series(1,3)"

1



2



3

But my result is:

psql -At -P recordsep="\n\n" -U postgres -d chronopay -c "select
generate_series(1,3)"

1\n\n2\n\n3



Simple newline not work too:

psql -At -P recordsep="\n" -U postgres -d chronopay -c "select
generate_series(1,3)"

1\n2\n3









--------------



psql -At -P recordsep='\n\n' -U postgres -d chronopay -c "select
generate_series(1,3)"

psql -At -R '\n\n' -U postgres -d chronopay -c "select generate_series(1,3)"

psql -At -R "\n\n" -U postgres -d chronopay -c "select generate_series(1,3)"

no resultat



Is it a bug?



p.s. PostgreSQL 8.1.5 on x86_64-unknown-linux-gnu, compiled by GCC gcc (GCC)
3.4.6 20060404 (Red Hat 3.4.6-3)





Thanks.

What this says is that there's no interpolation of escapes in recordsep.
Try putting them literally:

$ psql -At -P recordsep="
>
> " -c "select generate_series(1,3)"
1

2

3

"\n" is not a newline, it's a "\" followed by an "n".  You need to actually
enter two newlines

psql -At -P recordsep="

" -U postgres -c "select generate_series(1,3)"

or figure out how your shell makes escapes available.
