Sure, for instace with a function like this:
test=*# select * from apk ;
t
----------------------------------------------------------------------------------------
this is a long line with text, i will try to split this line to display
multiple lines
(1 Zeile)
Zeit: 0,251 ms
test=*# create or replace function split_line(t text,count int) returns
text as $$declare i int;c int; ret text; begin ret:= t; i:=0;c:=0;for i
in 0 .. length(ret) loop if substring(ret,i,1) = ' ' then c:=c+1; end
if; if c = count then ret := overlay(ret placing E'\n' from i for 1);
c:= 0; end if; end loop; return ret; end; $$language plpgsql;
CREATE FUNCTION
Zeit: 0,537 ms
test=*# select split_line(t,3) from apk ;
split_line
------------------------
this is a
long line with
text, i will
try to split
this line to
display multiple lines
