So I see your data now,
as a table on a mail, and as first glance I “see” that something is wrong,
But I need to reproduce your problem, so I need the data in such a way that I can copy paste.
So imagine I have a problem and I need you help me finding what is my problem:
I have this data:
CREATE TABLE edge_table (
id BIGSERIAL,
dir character varying,
source BIGINT,
target BIGINT,
cost FLOAT,
reverse_cost FLOAT,
capacity BIGINT,
reverse_capacity BIGINT,
category_id INTEGER,
reverse_category_id INTEGER,
x1 FLOAT,
y1 FLOAT,
x2 FLOAT,
y2 FLOAT,
the_geom geometry
);
INSERT INTO edge_table (
category_id, reverse_category_id,
cost, reverse_cost,
capacity, reverse_capacity,
x1, y1,
x2, y2) VALUES
(3, 1, 1, 1, 80, 130, 2, 0, 2, 1),
(3, 2, -1, 1, -1, 100, 2, 1, 3, 1),
(2, 1, -1, 1, -1, 130, 3, 1, 4, 1),
(2, 4, 1, 1, 100, 50, 2, 1, 2, 2),
(1, 4, 1, -1, 130, -1, 3, 1, 3, 2),
(4, 2, 1, 1, 50, 100, 0, 2, 1, 2),
(4, 1, 1, 1, 50, 130, 1, 2, 2, 2),
(2, 1, 1, 1, 100, 130, 2, 2, 3, 2),
(1, 3, 1, 1, 130, 80, 3, 2, 4, 2),
(1, 4, 1, 1, 130, 50, 2, 2, 2, 3),
(1, 2, 1, -1, 130, -1, 3, 2, 3, 3),
(2, 3, 1, -1, 100, -1, 2, 3, 3, 3),
(2, 4, 1, -1, 100, -1, 3, 3, 4, 3),
(3, 1, 1, 1, 80, 130, 2, 3, 2, 4),
(3, 4, 1, 1, 80, 50, 4, 2, 4, 3),
(3, 3, 1, 1, 80, 80, 4, 1, 4, 2),
(1, 2, 1, 1, 130, 100, 0.5, 3.5, 1.999999999999,3.5),
(4, 1, 1, 1, 50, 130, 3.5, 2.3, 3.5,4);
UPDATE edge_table SET the_geom = st_makeline(st_point(x1,y1),st_point(x2,y2)),
dir = CASE WHEN (cost>0 AND reverse_cost>0) THEN 'B' -- both ways
WHEN (cost>0 AND reverse_cost<0) THEN 'FT' -- direction of the LINESSTRING
WHEN (cost<0 AND reverse_cost>0) THEN 'TF' -- reverse direction of the LINESTRING
ELSE '' END; -- unknown
SELECT pgr_createTopology('edge_table',0.001);
With that data I am getting:
SELECT * FROM pgr_dijkstra(‘select id, source, target, cost, reverse_cost FROM edge_table’, 1, 15);
seq | path_seq | node | edge | cost | agg_cost

And this is an image generated from this data (my starting point is 1).

I don’t see your data, can you put the contents of the data
The only similar thing as “data” I have is your interpretation of a table contents.
This is the data:
SELECT ogc_fid as id, source, target, st_length(wkb_geometry)
as "cost" FROM linee;
