From: Stephen Frost Date: Fri, 12 Sep 2014 16:04:37 +0000 (-0400) Subject: Add unicode_{column|header|border}_style to psql X-Git-Tag: REL9_5_ALPHA1~1470 X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=a2dabf0;p=postgresql Add unicode_{column|header|border}_style to psql With the unicode linestyle, this adds support to control if the column, header, or border style should be single or double line unicode characters. The default remains 'single'. In passing, clean up the border documentation and address some minor formatting/spelling issues. Pavel Stehule, with some additional changes by me. --- diff --git a/doc/src/sgml/ref/psql-ref.sgml b/doc/src/sgml/ref/psql-ref.sgml index aa71674731..e7fcc734b5 100644 --- a/doc/src/sgml/ref/psql-ref.sgml +++ b/doc/src/sgml/ref/psql-ref.sgml @@ -1996,12 +1996,12 @@ lo_import 152801 the number the more borders and lines the tables will have, but this depends on the particular format.
