Hi. (CCing Michael Meskes) One of my customers asked me about what oracle compatibility mode in ecpg means, and I noticed current documentation does not explain ecpg ORACLE compatible mode (ecpg -C ORACLE) in detail. I myself learned the feature of "-C ORACLE" from regression test (src/interfaces/ecpg/test/compat_oracle) and source code.
Is lacking documentation intentional or do commit 3b7ab4380 and 3b9b7516f just forget adding the explanation? As for as I know, "ecpg -C ORACLE" is written briefly in ecpg command reference and PostgreSQL 11 release note, but they are not enougn information for users to understand feature of "ecpg -C ORACLE". https://www.postgresql.org/docs/current/app-ecpg.html ------------------------------- -C mode Set a compatibility mode. mode can be INFORMIX, INFORMIX_SE, or ORACLE. ------------------------------- https://www.postgresql.org/docs/11/release-11.html#id-1.11.6.21.5.9 ------------------------------- Add an ecpg mode to enable Oracle Pro*C-style handling of char arrays. This mode is enabled with -C. ------------------------------- On the other hand, informix compatible mode is written in detail. https://www.postgresql.org/docs/current/ecpg-informix-compat.html Best regards, Takeshi Ideriha
