call analyze from stored procedure in C

Hi everybody!

I have to insert a lot of data (more than 1.000.000 rows) in various 
tables. I use stored procedures in C to insert the data. It is necessary 
to run ANALYZE after inserting a some thousand rows into a table. Can 
someone tell me how to call ANALYZE 
(or analyze_rel(Oid relid, VacuumStmt *vacstmt)) 
from a C stored procedure ? Any help would be appreciated. 

Thanks
