A little lost but the first thing that stands out is that you are attempting to create an actual table instead of a temporary table. Not sure if that difference is meaningful to the function but procedurally is there a reason to create the permanent table instead of a temporary one?
If you do need a permanent table would you be able to generate the data as part of routine maintenance and/or via triggers instead of building out the entire (or portion) of the table each time?
I do not think you have provided enough code to get good feedback. The entire function would probably help – though maybe a simplified version but one that still exhibits the behavior in question.
You also do not provide the minor release level which may be relevant.

Subject: [GENERAL] EXECUTE of a 'create table' string is not happening
Hi,
I'm passing a tablename and two columnnames into a function so that I can SELECT Records in a FOR LOOP using 'fixed' field names.
Using the passed params I construct the create table command and then alter the names of two columns.
When I 'build' the function and then run my query to use the function w/ a different offset it works the first time.
The first time ONLY. But actually it doesn't work, it just doesn't error the first run.
Subsequent runs tell me that relation ######## doesn't exist, at the FOR...LOOP line, after ALTERing the table.
I build the string and it's good:
CREATE TABLE temp_gentokenstable AS SELECT businessid, publicname FROM businesscontact ORDER BY businessid OFFSET 200000 LIMIT 10000 ;
I'm forced to use v7.4.
If this is a known error, can I (with the version ; ^) ) get around it?
Ultimately I need to FOR..LOOP through through records and the table and cols will change. Any suggestions???
THANKS!
