Re: what are the ways to avoid --- "ERROR: EXECUTE of SELECT ... INTO is not implemented yet"

[Shantanu <shantanu(dot)gg(at)gmail(dot)com>]

Here is my real use case

1) We have nornal SELECT ...INTO calls in the procedure calls
2) However we landed ourselves with the following problem
http://www.postgresql.org/docs/faqs.FAQ.html#item4.19

<snip>

4.19) Why do I get "relation with OID ##### does not exist" errors when accessing temporary tables in PL/PgSQL functions?

In PostgreSQL versions < 8.3, PL/PgSQL caches function scripts, and an unfortunate side effect is that if a PL/PgSQL function accesses a temporary table, and that table is later dropped and recreated, and the function called again, the function will fail because the cached function contents still point to the old temporary table. The solution is to use EXECUTE for temporary table access in PL/PgSQL. This will cause the query to be reparsed every time.

This problem does not occur in PostgreSQL 8.3 and later.

</snip>

3) So the solution we are trying to implement is the EXECUTE command one. 

This is causing the SELECT ...INTO problem 


Upgrade is not an option :(

Currently the only available solution is 
Use a temporary table where we write the local variable and make it read from the table .

Any alternatives ?

PostgreSQL 8.3 includes support for EXECUTE ... INTO, so you may want to look at an upgrade.

Personally I wouldn't call this a bug at all. It's just that PostgreSQL knew how to parse that query before the support for actually executing it was written.
