Looking into this further, apparently the position of
if (verbose)
{
+ /*
+ * Show whether the table is permanent, temporary, or unlogged.
+ */
+ if (pset.sversion >= 91000)
+ appendPQExpBuffer(&buf,
+ ",\n case c.relpersistence when 'p' then 'permanent' when 't'
then 'temporary' when 'u' then 'unlogged' else 'unknown' end as
\"%s\"",
+ gettext_noop("Persistence"));
is not right, it is being called for indexes with verbose option also.
There should be an extra check for it being not called for index case.
Something like,
if (verbose)
{
/*
* Show whether the table is permanent, temporary, or unlogged.
*/
if (!showIndexes)
if (pset.sversion >= 91000)
appendPQExpBuffer(&buf,
",\n case c.relpersistence when 'p' then 'permanent' when 't' then
'temporary' when 'u' then 'unlogged' else 'unknown' end as \"%s\"",
gettext_noop("Persistence"));
Not sure, how do modify it in a more neat way.
