Apologies,

I am using SAS, a statistical package/database management system. SAS has
the feature of connecting to a PostgreSQL server. It does so by assigning
what is called a libname (a 'library' connection telling SAS that a
particular folder is a data storage). In this assignment, you specify the
server address, databasename, password. I.e. SAS connects to the server
and allows you to push data to/read data/manipulate data in the PSQL
database.

Here is the code in SAS:

# connect to the server and assign it the name 'psqlibrary'
libname psqlibrary postgres server='xxx.xx.xxx.x' port=5432
user=username password='xxxxxxx' database=dbname;

# then append data to the table 'table' in the psql database
proc append base = psqlibrary.table
data = datatoappend;
run;

SAS reports back error messages from the server if it receives such
errors. In my case, I repeatedly get the error described above. This
error is also reported in my terminal app if I log into the database at the
same time to monitor things there. I.e. as far as I can tell, the error "Out
of memory while reading tuples.; No query has been executed with that
handle" stems from PSQL itself. SAS prefixes the error with some specific
indicators such as "GLOBAL SYSDBMSG POSTGRES" or "ERROR: CLI describe
error".

Adrian, you are right, PSQL does receive the data. Also not sure what you
mean by cursor, I really new to PSQL... sorry!

Help much appreciated!
