database - postgresql won't accept a specific key -

-

so i'm using postgresql 9.5 store bunch of data in table named ids. data stored :

id1 (unique, not null) | bool1 | bool2 | bool3 | id2 (not unique)

id1 , id2 text variables. when try insert new data database use query :

"insert ids (id1, bool2, id2) values (%s, true, %s) on conflict (id1) update set interaction = true, id2 = %s;"

now when try insert specific id1 : c1316a6a-3bdd-4aeb-a1b6-b3044851880a__19 unique (i double checked that) database hangs. while using python , psycopg2 call query, if try insert key database hand (by connecting database via cli or gui) database still hangs.

however, if create similar database , use exact same command, works fine.

any ideas why hangs , how fix ?

edit :

thank you, a_horse_with_no_name

it indeed waiting transaction. killed pid , worked fine afterwards.

thanks again

i have postgresql db number of tables. if query: select column_name information_schema.columns table_name="my_table"; i list of columns returned properly. however, when query: select * "my_table"; i error: (programmingerror) relation "my_table" not exist 'select *\n "my_table"\n' {} any thoughts on why can columns, can't query table? goal able query table. you have include schema if isnt public one select * <schema>."my_table" or can change default schema show search_path; set search_path my_schema; check table schema here select * information_schema.columns for example if table on default schema public both works ok select * parroquias_region select * public.parroquias_region but sectors need specify schema select * map_update.sectores_point

asp.net mvc - breakpoint on javascript in CSHTML? -

-
i have .cshtml file has javascript tag. within script tag have few lines of javascript. first line of javascript refers property in @viewbag. other javascript lines plain script without mvc related references. observation: can place breakpoints (visual studio 2015) on each of these javascript lines. however, breakpoints has white dot in center of breakpoint symbol (red circle) except line @viewbag reference (this particular line not have white dot in center). it seems breakpoint without white dot hit during run-time. question: can explain going on here? white dot mean? why plain red breakpoint line line hitting breakpoint? the visual studio debugger expecting debug actual server-side code within .cshtml file opposed client-side javascript within it. iirc, visual studio allow debug javascript code expected in internet explorer (and possibly edge), other browsers want use either third-party tool or developer tools (f12) within browser. an easy approach take advant...
