PostgreSQL version: 13.10
Operating system: Ubuntu Linux 20.04.5 LTS
Description:
My system has numerous SQL scripts (each script contains multiple SQL
statements). Many of them look like
UPDATE ...
INSERT ...
...
VACUUM ...
These scripts are being run from a Java program, with AutoCommit=true, via
JDBC as:
Statement statement = connection.createStatement();
connection.setAutoCommit(true);
statement.execute(sql);
...
statement.getMoreResults();
...
This worked well for years until the server (not the client program) was
upgraded to 13.10. After the upgrade all compound SQL statements with VACUUM
at the end fail with this error:
09:48:56.585 SEVERE Script processing failed:
org.postgresql.util.PSQLException: ERROR: VACUUM cannot be executed within a
pipeline

JDBC driver version is 42.3.3 (i tried the latest 42.5.4 and it doesn't make
a difference).
The same SQL scripts are still working with the latest postgresql 14.7
