7.4.6 on Linux.

I need a way to drop all indexes of a table without knowing the names of the
indexes.

Say I have a table

table1
index1
index2
index3

I don't want to do

drop index1;
drop index2;
drop index3;

but I want

drop <all indexes of table table1>

is this possible? I looked in the manual at pg_index, but couldn't build an
sql string to do it.

Thanks

if your are using default namespace (schema)
% tcsh

% foreach i ( `psql -t -q -c "SELECT ci.relname from pg_index i,pg_class
ci,pg_class ct where i.indexrelid=ci.oid and i.indrelid=ct.oid and
ct.relname='YOUR_TABLE_HERE'"` )
foreach? psql -c "drop index $i"
foreach? end
