Hello,
This has me befuddled. I am trying create a simple experiment, rather
new to SQL and I am running into an issue with single quotes. All I can
find on creating a function states the procedure should be contained

Hello Jasen and the List,
I tried the $$ quote suggestion:
create function f_csd_interval(integer) returns interval as

BEGIN
RETURN $1 * interval '1 msec'

Here is what I got:

Kretschmer was quite close, try following:
case
when trim(coalesce(s1,'')) = '' and trim(coalesce(s3,'')) = '' then ''
when trim(coalesce(s1,'')) != '' and trim(coalesce(s2,'')) != '' and

I have 2 tables T1 and T2
T1 has the columns: D, S, C. The combination of D,S,C is unique.
T2 has the columns: D, S, C, and boolean X. The combination of D,S,C is
not unique.
I need to produce the following result for every occurrence of T1:
D,S,C, COUNT
COUNT is the number of matching D,S,C
I might be missing something but does this solve your issue?
CREATE TABLE t1(d INT,s INT, c INT);
CREATE UNIQUE INDEX idx01_t1
ON t1 USING btree (d, s, c);
INSERT INTO t1 (d, s, c)
VALUES (1,1,1),(2,2,2),(3,3,3),(4,4,4);
CREATE TABLE t2(d INT,s INT, c INT, x boolean);
INSERT INTO t2(d, s, c,

How about this?
CREATE TABLE t1(d INT,s INT, c INT);
CREATE UNIQUE INDEX idx01_t1
ON t1 USING btree (d, s, c);
INSERT INTO t1 (d, s, c)
VALUES (1,1,1),(2,2,2),(3,3,3),(4,4,4),(5,5,5);
CREATE TABLE t2(d INT,s INT, c INT, x boolean);
INSERT INTO t2(d, s, c, x)
VALUES
