play with current schema

Hi,<br /><br />this may not be the right place to address this question but I've already subscribed on this list.<br
/><br/>I'm connected as user "def" and here's what happens while modifying current_schema - i.e. search_path var : <br
/><br/>##########<br />db=> \dn<br />       List of schemas<br />        Name        |  Owner  <br
/>--------------------+---------<br/> abc                | abc<br />[...]<br />db=> select current_schema();<br
/> current_schema<br />----------------<br /> public<br />(1 row)<br />db=> show search_path ;<br /> search_path 
<br/>--------------<br /> $user,public<br />(1 row)<br /><br />db=> SET search_path TO abc;<br />SET<br />db=>
selectcurrent_schema();<br />  current_schema <br />----------------<br /> <br />(1 row)<br /><br />db=> show
search_path;<br /> search_path <br />-------------<br /> abc<br />(1 row)<br />###########<br /><br />Trying to change
thecurrent schema to a _not owned_ schema will _not_ raise any error and result in this 'misbehaviour' between the two
commandsshowing the current schema. <br />select current_schema() will return NULL ...<br />Did I miss something or
everything'snormal here?<br /><br />Isn't it supposed to raise an error or succeed and then the two commands would
displaythe same?<br />However, what's the difference between those two commands except that the latter is a variable
andthe former will pick up stuff from catalog's table? <br /><br />Thanks for help<br /><br />Charles<br />
